Unfortunately, few details about the Xbox 360 game are available at this point, with Funcom only saying it will definitely come well after the PC version ships, which is expected in the March-to-May 2007 timeframe. It's also not determined yet if Xbox 360 players and PC players will be able to co-exist on the same servers-but Funcom wouldn't rule it out either.
In the meantime, though, TeamXbox can give you a rundown on what the game will hold based on an early demo of the PC game, which has been in the works for about three years. Though definitely an MMORPG by design, the game's makers have decided to go off the traditional path in many ways. The hope is to create a game that will stand out.
