Well yea, the demo wasn't mind blowing, I was more gonna get the game for the co-op, which actually looks really fun.
If you want a solid game though, go play the first 2 BioShocks. Ultimate Rapture Edition (games 1, 2, and all their DLC) is only $30 right now. One of the best deals in games I've ever seen for the content it gives you.
