Lulfas writes "Worlds.com today sued NCSoft over its patent on a scalable virtual world, filed in 2000 and granted this February. This is a very broad base patent, and there is no reason to expect they will only sue NCSoft, when they should be able to use the same patent against other companies. 'Specifically, the suit claims that NCsoft has infringed on patent 7,181,690, "System and Method for Enabling Users to Interact in a Virtual Space" through its games, including City of Heroes, City of Villains, Dungeon Runners, Exteel, Guild Wars, Lineage, Lineage II, and Tabula Rasa.'"

<em>Tabula Rasa</em> Promotion To Send Gamers' DNA to Space 90 comments
Bridger tips news that NCSoft's Tabula Rasa, created in part by Richard Garriott, is running an unusual promotion right now. Garriott is going to the International Space Station on October 12th, and he'll take with him a digital record of the DNA of various players and celebrities. The basic plot of Tabula Rasa is that Earth was attacked and humans almost completely wiped out. Garriott's promotion is playing on that idea; the hard drive with the DNA data will be left in orbit "just in case" something happens to humanity on Earth. NCSoft has been running a variety of polls and contests to include further data about humans on the hard drive. The deadline for joining the project has recently been extended to September 29th.

<em>Tabula Rasa</em> To Shut Down 244 comments
NCSoft announced today that it will be closing down Tabula Rasa on February 28th. The sci-fi shooter-flavored MMO struggled for quite some time, despite recent attempts to draw in new players by announcements of new features, price reductions, and using Richard Garriott's trip into space as a promotion. We discussed Garriott's departure from NCSoft a couple weeks ago. This is NCSoft's second failed MMO, and apparently layoffs are in the works. They seem to be making an effort to make the game's last few months as fun as they can for their remaining players, though. "Before we end the service, we'll make Tabula Rasa servers free to play starting on January 10, 2009. We can assure you that through the next couple of months we'll be doing some really fun things in Tabula Rasa, and we plan to make staying on a little longer worth your while."

Also, I think MUDs read on at least some of the claims, and at least some of the others
EQ might be better than UO for this one. . . (Score:5, Informative)
If you look at the link to the actual patent, and begin reading the claims, this does not apply to the (original version of) Ultima Online, or to text muds, because the patent specifically describes a 3-dimensional graphical world as being part of the claims. UO is (or at least was, last time I played it around 2001 or 2002) 2-dimensional. Right about the time I was leaving, they introduced an expansion called Third-Dawn, which still didn't make the world truly 3D, but it did make player avatars and monsters 3D, IIRC.
EQ, as I recall, was true 3D (I only played a trial account for like 10 days once, so my memories are rather vague), so it might be a good candidate for prior art.
It should be noted that the patent does not appear to cover (I don't know for sure; I'm not a lawyer), the idea of a 3D MMO, per se, but rather a few necessary client rendering techniques (which, in reality, almost any 3D MMO would be likely to employ) for determining what other users' avatars should be displayed by the client. It appears the idea they are trying to patent is that, in a 3D world, when you turn the camera to look a given direction, you should only see some avatars, and not others (that is, only the ones in your field of view). Additionally, if there are a lot of avatars, this patent claims protection for the idea that the client can implement a maximum number of avatars to display, and to use the knowledge of the maximum number to display, combined with the position information, to determine some subset of the avatars to display (presumably the X nearest avatars, where X is the maximum number to display, though the patent doesn't specify this explicitly).
I'd be shocked if EQ and Meridian59 didn't both do these things several years before this patent app was filed.
I'd also like to point out, that the patent doesn't specify 'camera orientation' or 'client view orientation' (even though that appears to be what they are trying to cover), but rather 'avatar orientation' (which suggests to me that this patent would only apply to MMOGs where the camera orientation is locked to the avatar orientation). Based on my 3+ years of playing CoH, I can tell you that the CoH client doesn't determine which other avatars to show on screen based on the orientation of my avatar - I can spin the camera freely to point in any direction, even look completely backwards from the direction my avatar is facing, so I suspect that NCSoft could claim that as a defense, if they had to.
Also, I think they could, maybe, make a defense against claim 6 (I'm not sure though):
Now, I could be wrong here, but I thought most client/server 3D game protocols do *not* have the clients transmit the position of the avatar to the server, which is part (b)? Don't the servers already know the position of the avatar, and the clients just send a vector, that is, a request to move a certain number of units in a particular direction, at which point the server calculates a new position from the original posti

Re:EQ might be better than UO for this one. . . (Score:4, Insightful)
I've seen several parts of the patent that are not applicable to certain games or have prior art.
Article 4 about determining the subset of avatars to display would absolutely not apply to Dungeon Runners or Guild Wars, which are instanced. I can't remember how Dungeon Runners did towns (I played it all of 2 hours), but GW has district maximums to never overload towns and thus never needs to use nearness to display avatars.
Patent filing is 2000, NCSoft's own Lineage was released in 1998 and is 2D (Lineage II was 2003 and true 3D).
The Realm and Meridian 59 both were true 3D and predate this patent. Several other non MMORPGs that were also 3D and had an online component also predate this patent, but don't have the nearby limiting display issue.
And yes, as parent stated, clients aren't trusted in MMORPGs, so the server handles all movement and momentum, however, I did see source for one (FOSS MMORPG) 'hint' about where the client thought it was to deal with lag issues (which may be patent infringing). From the games I've played, however, that is not the norm and you rubber band to wherever the server thinks you are. Incidentally, most I've seen wouldn't trust a game to pass a vector - just a direction and a mapping of keys and buttons. Server handles velocity and momentum as well as absolute position.

Re:EQ might be better than UO for this one. . . (Score:5, Informative)
Being an avid MMO player from UO to current, as well as being a 3D developer on the Unreal Engine, I can make for some useful input here.
The original UO was indeed a 2D isometric client. Third Dawn brought 3D aspects to the game, though the world was still rendered in isometric view. It just looked more 3Dish. There were however mods/ports to UO that rendered a 3D world! They were buggy as heck though, but you could (in theory) play in the UO world with a 3D client. (Though it was a third party client).
Now, EQ was a true 3D world. No if's or but's about it.
The whole bit about the number of avatars to display, that's more really related to engine/hardware performance. Basically, when developing an environment developers need to look at polygons on a screen. This is one of the main restricting factors in developing a world. The more polygons a graphics card has to render, the longer it takes. It's not the only thing, but at the time that this patent was filed, it was certainly one of the most important things.
Now, avatars in a game generally have a much much higher polygon count than the environment around them, so naturally restricting the number shown might be very beneficial to rendering a game world nicely, however, soon after this patent was originally filed, a bright spark came up with the idea of not removing entire actors, but adding a LOD factor into models. Basically, it means that the further something is away from the camera, the less polygons it will use. This can also be ingeniously used to reduce the polygons per actor/model in the camera view if the number starts getting too high.
To use the obligatory car analogy, if I want to limit my game engine to displaying 100 polygons on the screen at a time, I can render a car with 100 polygons, but also allow the code to reduce these polygons to 50 if a second car comes onto the screen. Should I need to have 10 cars on the screen at once, they would each be reduced to 10 polygons.
Don't the servers already know the position of the avatar, and the clients just send a vector, that is, a request to move a certain number of units in a particular direction, at which point the server calculates a new position from the original postion + the vector?
The section you write about actors and client/server relative positions is sort of right. It's not far off anyhow. Here is how things work in just about all client/server applications now.
The server sets the original position to the client - when a new level loads for example. The the client sends data as to where it wants to go and both the server and client move the character around. Now, due to a number of factors such as latency, packet loss as well as a number of others, the two locations will become out of sync. However, rather than the server being updated with the client's location, what happens is that the client is updated with the server's location of where it things the character is. This sometimes leads to what is known as the "slingshot effect" where characters (or other actors) suddenly update in the client view and appear to slingshot around the screen to catch up. A notable exception to this rule is World of Warcraft, which does actually have servers that will quite happily allow a character anywhere in the world that the client lets them get. This has resulted in some rather funny "exploits" where people altered their clients and walked past mobs to get to the final boss in an instance and then just started attacking it. This may have been fixed in one of the expansions however. While I am not entirely sure, I think that D&D Online may have also suffered from the client updating the server with actor locations, as I recall there was a considerable number of movement hacks and exploits in that game.
