Bioshock is a waste of time...it looks nice but the gameplay is repetitive and linear.

I'd try out the &quot;Orange Box&quot; (HL2: Episode 2, and Team Fortress 2) from Valve if you like shooters.  You also get the Episode one and I believe HL2 itself and all the stuff that goes with it.

Or, if you'd like some first person RPG action try Oblivion and its expansions.

I just bought Medal of Honor: Airborne, and it is pretty sweet as well.
