Role-playing games have drawn a great deal of inspiration from classic tabletop games--you create a character, then go on adventures to fight monsters, acquire treasures, and gain experience levels. Many computer games focused on hack-and-slash action, and when role-playing games went online with games like Diablo and EverQuest--with the prospect of adventuring alongside other players to take on even more challenging foes--they seemed even more exciting and harder to put down. ArenaNet's Guild Wars, however, will turn its focus to something else entirely--player-versus-player (PvP) battles, in which you'll do most of your fighting against teams of other human players. Though the upcoming game will still let you go off on leisurely hack-and-slash adventures, it will put much more of a focus on strategy and tactics.
