If Guild Wars reminds you a bit of Blizzard's classic Diablo action role-playing games, that's probably because developer ArenaNet was founded by Blizzard veterans. While Guild Wars isn't a massively multiplayer, persistent-world game like EverQuest, the goal in the game is to explore a vast, virtual world while battling both computer-controlled enemies and other players. However, Guild Wars will require you to do a lot more than just rapidly click on the mouse button to hack and slash your opponents. The game also incorporates a vast and intricate skill-based system reminiscent of the card game Magic: The Gathering. Each character can have dozens, if not hundreds, of skills in his or her inventory, but prior to each adventure, you can only select a handful of those skills to bring along. We had the chance recently to ask producer Jeff Strain how the gameplay in Guild Wars will adjust to accommodate veteran and casual role-playing gamers.
