Demos for Enslaved: Odyssey to the west and Arcania: Gothic 4 hit Xbox live marketplace recently... I was curious about both these games, so it was nice to get demos of them. Enslaved looks really promising, but I think I will rent rather then buy. Arcania seems to be good too, but being an RPG, the demo is quite slow paced.
As for what I am playing... I am wrapping up the odds and ends in Mafia II, then I will play the DLC. Hopefully i can finish it up before Dead Rising 2 gets here next week. :-D
