Ok, so I figured I definitely needed a thread all to myself on this.

I play my PS3 occasionally but I'm looking to pick up a game to play over Christmas (and beyond as well). I am just looking for some suggestions. I'm not looking for a sports game, final fantasy type crap, or a realistic war game like Call of Duty. I loved Bioshock and would definitely be interested in something along those lines. Bizarre worlds or anything unique in any way. Doesn't have to be exactly that though. Maybe Assassin's Creed III? Or is there some other great game that is unique and not completely insanely difficult?

Basically I am just out of the loop with video games and I am wondering what could be a good option for someone like me. Any thoughts? Thanks for any suggestions!
