Using Math To Tune a Video Game's Economy 96

An anonymous reader writes: When the shipping deadline was approaching for The Witcher 3, designer Matthew Steinke knew there was a big part of the game still missing: its economy. A game's economy is one of the things that can make or break immersion — you want collection and rewards to feel progressive and meaningful. Making items too expensive gives the game a grindy feel, while making them too cheap makes progression trivial. At the Game Developers Conference underway in Germany, Steinke explained his solution.

"Steinke created a formula that calculated attributes like how much damage, defense, or healing that each item provided, and he placed them into an overall combat rating could be used to rank other items in the system. ... Steinke set about blending the sub-categories into nine generalized categories, allowing him to determine the final weighting for damage and the range of prices for each item. To test if it all worked, he used polynomial least squares (a form of mathematical statistics) to chart each category's price progression. The resultant curve (pictured below) showed the rate at which spending was increasing as the quality of each item approached the category's ceiling value."

    As you say, you want to feel like your economic choices have consequence, and not just for your pocketbook. If I buy all the fish in town, then not only should the price of fish go up, but the fishing industry should spend its money in predictable locations and boost other industries.

    As my subject line alludes, the real place this crops up again and again is in space games. If I'm buying and selling the complete available product of a planet in some particular industry, that should have significant effects. Or, if I blow up a bunch of cargo ships carrying spaceship parts, then that should have significant and immediately noticeable effects. Instead, none of this is true at all in basically any game but EVE.

    • The common audience for these games wouldn't appreciate such nuance/sophistication. EVE is very much a "geek's" game. EVE's complex economics and politics tends to drive away the casual/braindead players.

        Congrats, you just described every computer game ever.

      • EVE is overrated - it's just a libertarian fantasy-land without any of the truly damaging human consequences.

        Yes, EVE's problem is that it allows player 1 to be a complete dick about things, screw you over, and totally get away with it.

        There is no real justice, it is like the wild west, but without the ability to hunt that player down and kill them.

        If you behave in the real world the way players behave in EVE, you wouldn't live very long. Sooner or later, someone would simply shoot you and be done with it.

        • In the Wild West most people wouldn't hunt down an individual that wronged them. They'd report it to the sheriff who would post a wanted poster which would attract bounty hunters to go hunt down the criminal.

          EVE lets you place bounties on other players.

          • The character is not jailed or perma-killed (barring stupidly not saving off a clone copy with your skills, which would almost never happen for an experienced player) and all their stuff not seized and sold off.

            There is no real downside to griefing, which is part of the problem with more open PvP games. Indeed, the companies rely on casuals to provide fodder for hardcore griefers, going back to Ultima Online.

          • Those bounties would mean something if they were permanent.

            If you faced permanent death from your stupid behavior, you may be more inclined to be nicer.

            Not everyone of course, after all, you did still have to deal with it in the real world, but you always did have that as a solution.

            EVE just supports people who like to be trolls from the safety of their homes and computers, which is fine I suppose. It is the same type of people who troll forums behind fake names.

            In the really real world, shipping is protected by threat of military action.

            EVE is a cheesefest because there is insufficient motivation to provide stability.

This irritated me, so I went and "told" the two main guards at the entrance about it. (I attacked one and trained them past the elf and let them kill me.) Then they wandered back past the elf, who they faction-hated, and, being 2 rather than 1, took care of business.

            After doing this a few times, a GM "warned" me.

      X3 came close-ish to achieving it. The price of a good was relative to the available stock. Some stations consumed certain items to make others so over time their stock levels would drop and they would offer more and more money to restock. Energy cells were the base resource used by most stations so they were a good place to start in the economy.

      The real problem though was there was no real top end consumers creating enough demand so the game dumped resources at various points to keep everything moving. And it was too easy to dominate the whole economy with a super station. Your personal business empire kept expanding but nothing else did. If you picked one of the unknown sectors to build your base you became an economic god with nothing that could stand in your way.

      • Some stations consumed certain items to make others so over time their stock levels would drop and they would offer more and more money to restock.

        Yet the price of what those stations produced didnt reflect the prices of the raw materials needed, and stations making what should be large profits just swallow the money into oblivion, and when stations should be out of money they magically have an endless supply anyways.

        The elephant in the room is that its not an economy. In an economy the actors are each trying to benefit from their transactions, most transactions are wins for both parties, consequences when they aren't, motivation to eliminate losse

All people really wanted was a rewrite of the original engine to handle multiple threads so that they could actually run a full economy. Lets not even talk about what we got instead....

        • Agreed. One point though is that the price of an input is no determiner as the the price/value of a final product. Price of a final product is a function of supply vs demand. Of course if your final product is worth less than the inputs you will go broke, but that too is reality.

              The thing is, markets both have inherent mechanisms against indefinitely growing wealth inequality and their own periodic corrections. First, there are diminishing returns to higher levels of wealth due to the difficulty of managing it and declining profit margins with higher wealth. Large businesses and mutual funds have run into this before.

The hard part is designing an economy that both works and makes sense, with no cheating. All the money has to go somewhere and do something that makes sense, that's non-trivial. Economists argue over how economics works in the real world as it is.

      Yep, it annoys me a bit when at the beginning of a game, it costs a gold coin to stay a night at the inn at the beginning of the game, but it costs 100 gold coins at the end of the game in the "end game" areas. Granted, these are not games that are attempting any sort of "serious" world-building like Witcher 3. It still seems lazy, though - they should use other means for removing money from the player.

      I've also thought it somewhat lazy for developers to have a single coin type (typically "gold coins"). I've always thought that designers who resorted to that sort of currency never really understood how incredibly valuable a single gold coin actually is. Common goods are typically highly over-valued, and weapons and armor actually tend to be undervalued. It's ridiculous for a fish to cost 5 gold coins while a sword, even a basic starter sword, might only cost 100. Granted, I think most gamers don't really care about such things, but just once I'd like to see a videogame at least attempt to make a realistic stab at this.

      MMOs (particularly "theme park" types) have a particular problem with their economies, in that goods are essentially created from nothing in limitless supplies, and the final products from crafting last an infinitely long time. As such, they need to figure out how to create viable viable "gold sinks", or ways of removing money from the economy in ways that doesn't irritate the players too much. I've always thought that, no matter the solution they came up with, it always ended up feeling rather artificial (or simply inadequate), and it often ended in a massively inflationary economy.

      I'm still working my way through the first two Witcher games. As soon as I'm ready to play the third, I'll have to take some note of the general economy and see if it ended up as satisfying to play as one hopes.

      • Most modern MMOs don't have a real economy. EVE Online is a rare exception (and very much a niche proposition). Of the "normal" MMOs, then depending on who you talk to, Final Fantasy XI (released 2002 in Japan, 2003 in the West) or Star Wars Galaxies (2004) was the last to allow any significant degree of player freedom to shape the economy. Everything since World of Warcraft has locked in-game financial transactions down so hard that actual trading between players is knocked right out to the margins.

        What do

        • What do I mean? Basically, that the items of highest value in most MMOs cannot be obtained through player-production and in-game trading. In a subscription MMO (eg. WoW, Final Fantasy XIV), the most powerful gear will normally be obtained by players through skill-based team challenges (high-end raiding or PvP). Once obtained by a player, it is almost always locked so as to be untradeable to other players. A second tier of good-but-not-best gear is usually available via a pseudo-currency (tokens, honour, whatever) that is rewarded in fixed proportions from performing repetitive activities (daily quests, dungeons etc), often with a cap on how much can be earned in a week, and which can't be traded to other players. Consumable items are still crafted and traded, but the trend in MMOs has been to downplay these over the last few years.

          Crafted gear in FF14 is frequently the best or second best option assuming you have the patience/money to acquire the item and meld it. Crafted accessories are flat out the best option for tanks. The fact that the best gear can't be obtained on a market board shouldn't be particularly distressing in an MMO. That gear is the way to let people know that you are able to clear the toughest content in the game.

Values automatically track up and down based on supply and demand... am I oversimplifying the problem, or is the original article overcomplicating it?

    I don't get what an "economy" has to do with this. It's a single player game and just how they calculated item costs. And that's it... nothing new and sure as heck not an economy. You'll note tons of games, multiplayer or not have static prices for items and this sounds like just another way of calculating those prices. It's not an economy.

    • A single-player game just needs to *simulate* an economy, meaning that you need to ensure there isn't some loophole that allows the player to gain an infinite amount of loot through some simple, expedient task. In a real economy, prices are adjusted according to supply and demand, of course. It's a natural feedback mechanism that ensures such "loopholes" are very short-lived.

      So, the question becomes "how do you set prices so that it *appears* a real economy is at work, rather than just a designer arbitrar

    I originally read the headline as "Using Meth to Tune Videogames" and thought that explains a lot.
  • Wait a minute here. Is there an editor so clueless that they thought the notion of a game developer "using math" is headline-worthy? What's next, a story about how "programmers" are "using math"?

    I'll bet they used "physics" and even "engineering" too!

    What the hell?

    • As a professional videogame programmer, I can assure you that it's fairly newsworthy when a game designer uses math to solve problems like these.

        There's more math in the corniest Free2Play game than there is in Witcher 3.

        As a professional videogame programmer, I'm guessing you've heard of Eve Online. I'm just guessing here, because I'm not a professional videogame programmer, but I'll just bet they used a little math in the same way. Over a decade ago.

        Anyway, my point was that I would have thought Slashdo

          I'm exaggerating a bit, as I was going for a humorous remark. So, killing the joke dead and answering your question seriously, yes, I've heard of Eve Online, and know quite a bit about it, but haven't played it. In terms of economies and designer math skills, MMOs are a slight exception. They take their in-game economies very seriously, and some are known to hire actual economists to help guide their virtual trade and monetary policies.

          Designers don't necessarily avoid math, but they often use it in ways that drives programmers insane. For instance, they'll use formulas in spreadsheets to calculate tables of figures for loot, armor, damage, etc, and then painstakingly enter all those figures by hand. Why? This allows them the freedom to individually tweak components as desired. Programmers look at this and shake their heads, because we're hardwired to avoid that sort of redundancy whenever possible. For whatever reasons, some designers seem to revel in it.

          Many designers tend to be control freaks. They're deathly afraid of automatic, feedback driven, or chaotic systems (all of which could apply to an economy), and often for good reason, as some outlier condition could tend to cause autonomous systems to spiral out of control. This is why most MMO in-world "economies" are tightly controlled affairs, with lots of limiters to prevent things from going too far in any particular direction too quickly. Programmers are always suggesting ways to create automatic and chaotic environments driven by algorithms, but designers want carefully scripted and planned systems, because they want to control and tweak it.

          From the description, it appears this designer only turned to math as a last resort, because there was simply no time to do the sort of hand-tweaking that designers typically do. They were impressed enough with the results (gosh, math actually works!) that they wrote about how they did it. And the programmers on the team are probably thinking "I told you so. In fact, I told you so years ago, and you only listened to me when your back was up against a wall."

    Magic Online, the digital version of the famous trading card game, is currently undergoing a kind of "economic recession". Basically, trading for cards is facilitated by event tickets (roughly $1 in value) and booster packs (containing 15 cards, roughly $4 in nominal value) that act as a digital currency. Events are entered using event tickets as payment and they pay out as booster packs to the most winning players. This is done to avoid gambling laws.

    What has happened is that number of players entering events has gone down while the amount of booster packs floating around has increased, so that the going price for booster packs has fallen to around 2 tickets (so $2 equivalent). This has made entering events unattractive for all but the top players, since the expected value of the prizes to win are now half of what they should be, while the entry fees remain the same. This further drove the number of players down, with many people selling their collections and leaving Magic Online.

    Several months ago Wizards of the Coast set up an "economy strike force" that supposedly consisted of several people with "advanced math degrees" to solve this conundrum of a depressed economy. They finally announced their "solution" some weeks ago. It was to double the entry fees and basically cut the prizes to 75% of the old one.

    The economy predictable tanked even harder, leading to more players selling out.

      I find this ironic as NPR recently praised the MTG team for their economic skills. [npr.org]
