"Dungeon Siege II is all about party-based combat ... we want to give the player more choices," Lambert explained, firing up a demo. Gas Powered Games also listened to fans to give them what they wanted: in particular, more story! Characters now have deep backgrounds and the world is fully fleshed out, more akin to classic Bioware RPGs. Characters have their own likes and dislikes, and may attack one another if they get on each others' nerves.
