Although Dungeon Siege isn't one of my all-time favourite games, it certainly is fun! And the sequel doesn't look too shabby either:

I recommend watching the video narrated by Chris Taylor. Improved character development, training pets, powers, dual wielding, different skills... at least now instead of each fighter/archer/mage being pretty much the same, we'll be able to personalise each one more, so that each fills a different role.

Since it appears to be Dungeon Siege, but with more traditional RPG elements in it, it looks like it could be pretty good. This is one game that I'm certainly looking foward to!
