I got the novella thing with the game and have read the first couple of pages, it's confusing but I think that you play as a child raised by the Divine One (your character in the first game). I could have actually got the game yesterday (Wednesday) but forgot... there's a store here (sheffield) that sells games as soon as they get them in stock, regardless of release dates, and I use them.
Some more notes: I never played the demo but the first area of the game the game runs really slowly. Not choppy, just really slow... like the characters are running in slow motion. This changes when I go to the tunnels or something and there's less to display on screen - then they run quickly. This is annoying, as I have a 3Ghz P4 and Radeon 9700 pro so it really shouldn't be running like this. Plus it doesn't seem jerky, just like they're running through treacle. Any advice?

Another question: I read lockpicking isn't that useful in this game, are there always keys for every locked item? If so I'll find the keys and ignore the lockpicking skill. Though on the very first screen I can't find the key for that chest that's outside your cell. Voice acting is great. Death Knight is overacted but the other voice acting is high quality.
