I thought the demo was decent, and I don't know a whole lot of games in this style that are significantly better this gen. Infamous, sure. Bourne, maybe? Stranglehold, as others pointed out, was a chore. I'm really at a loss for non duck and cover 3rd person shooter games that are great so I can't bag on this game much.
That being said, it's more of a rental than a buy unless the game is of decent length and has ample behind the scenes videos of Eliza Dushku.
