Dungeon Siege: Legends of Aranna
I picked this up and I'm playing through it - I finished the first one (there aren't many games that I actually finish) and it's cool going back through another world built with this awesome game engine.
One of the most impressive things about Dungeon Siege is it's pathing. You can click pretty much anywhere and if there's a way for your character to get there, it will, using the shortest possible path. Even for something fairly complicated like clicking outside a house when you're currently inside it and two stories up.
And, well, the graphics are awesome.
