I haven't had one yet, but I only got my 360 last December.

I played the demo of the first one, it was pretty bad. I'm really not looking forward to the next game. I find it silly that enemies can snipe you from long range (100m+) with assault rifles and your AI buddies can't seem to shoot straight in any situation whatsoever. Worst game in the franchise, it should never have been given the 'BattleField' name.

Bioshock. I don't get what the big deal is. System shock 1 & 2 were way better. The only part I liked was the dentist level with the crazy nurse, the rest was boring. I finished it, but only because I forced myself to do so.
