Bioshock was really good, I really enjoyed it. Not quite as much as I enjoyed CoD4, but I could never just pick up and play. The story is quite complex and the missions require quite a bit of thought and planning. Only other thing is, towards the end of the game, the enemies get easier because you level up, but they don't seem too. Anyway, it's pretty much a must for anyone with a 360... Gers of War I never got into, short story, not many peopl online and just didn't live up the hype for me.
