0 A.D. Goes Open Source 88

DoubleRing writes "Wildfire Games has announced that it will be moving its previously closed development process for 0 A.D. to open source. All code will be released under the GPL and all art under CC-BY-SA. 0 A.D. is a historically-based RTS, and while it's not yet complete, this trailer is purportedly actual gameplay footage. With a codebase of over 150k lines of C++ code plus 25k lines in development tools, this is looking like a fairly promising entrant into the open source RTS field. The screenshots are definitely pretty, to say the least."

        Coders with enough time and skills will look at the code. If they will find things that can be improved they'll improve them, if they find things that can improve other games they will port them. Open sourcing stuff is like allowing people to communicate, before we have each person and his/her own idea, after we have each one evaluating others perspectives. That's how human knowledge progresses.

        • That sort of approach is wonderful for science, since science has a target: the true state and function of the universe. But it's not so simple for something that amounts to a work of art like a game. There is not an absolute target; the target is arbitrary fiction. Without good central leadership the artistic expression risks becoming fragmented. Now, I'm not saying it's impossible for the open approach to work, but suggesting that it's equivalent to the progress of human knowledge is missing an important complication.

        Nor was it ever AD 1 in any sense other than retroactively. Wednesday, the 28th of August, Diocletian 247 was immediately followed by Thursday, the 1st of January, AD 532. (The Diocletian calendar started with August 29.)

        Retroactively, 1 AD, the 1st of January was a Saturday, so the last day of BCE was a Friday. TGIF! (cal 1 1)

      If you would read the FAQ [wildfiregames.com]:

      Are you aware that the year 0 A.D. did not technically exist?
      Indeed. Think of 0 A.D. as a hypothetical time period that never existed. It is a snapshot in time where major players of the classical ages were placed in an observatory. This is your chance to see them 'duke it out'. Your job as the player is to create the hypothetical and recreate the historical.

              Fine. They magically created the concept of "0 A.D." to illustrate that while attempting to be historically accurate, it is still essentially fiction and fantasy ultimately designed to be fun. How's that? Good enough for the ol' ego? Okay, wait, I've got a better one...

              The only reason there wasn't a year "0 A.D." is because the people who created the calendars back then weren't as smart as you are and didn't fully understand the concept of zero-offsets, and this game gives you the chance to see what an ancient civilization -- including its calendar -- would have been like if they had been ruled by someone so amazingly intelligent that mentioning "0 A.D." in the context of the real history that was not ruled by their stunning intellect is, to them, insultingly dumb.

              There ya go. That has to be at least as good as invisible entryways to magic universes, which I should point out is implicitly implying that you, a stupid muggle, are too dumb to see even when crowds of rambunctious children vanish into them.

                Actually, retroactively re-dating the dates before AD 1 wasn't considered until the Anglo-Saxon historian the Venerable Bede, who was familiar with the work of Dionysius, used Anno Domini dating in his Ecclesiastical History of the English People, finished in 731. In this same history he also used another Latin term, "ante vero incarnationis dominicae tempus" ("the time before the Lord's true incarnation"), equivalent to the English "before Christ", to identify years before the first year of this era, thus establishing the standard of not using a year zero (i.e. ordinal, not cardinal numbers), even though his work did show that he did grasp the concept of zero.

            Well, the game developers did actually:
            "How historically accurate will 0 A.D. be?
            As much as we can make it. Our dedicated historians oversee all of our content to ensure it's historically accurate. Ancient history is a rich resource to exploit, and we hope to promote greater interest in it. However, there are various factors we have to take into account that won't allow us pure realism and authenticity:"(insert obvious things related to this being a game).

            Which still makes "0 A.D." a silly thing to find requiring an ego-destroying suspension of disbelief. I think it works perfectly to both establish the game's period in history, and to designate that it is still outside of that history and somewhat fantastical as a game requires. The name works by assuming you are aware that the date does not exist, rather than assuming ignorance.
