Sa-WEEEET!
Makes me wonder if they're going to use a newer D&D ruleset. Wouldn't be surprised, but don't really care either way. Care more about the story than the mechanics.
And yeah, you definitely owe it to yourself to play them. The first one is decent but 2 is just pure awesomeness. Pained me when they moved away from the Infinity Engine's gorgeous 2D backgrounds to Neverwinter Nights' fugly, tile-y 3D environments.
