Assassin's Creed 1, 2 and Brotherhood: all great games and fun to play.

Oblivion: Best RPG there is. Skyrim will be Awesome, as Bethesda does a great job in RPGs.

Call of Duty: Don't play them, but some are good. Also there are too many of them.
Grand Theft Auto: Don't play them. Also there are too many of them.
Fifa: No idea what it is

Halo: the third Halo and Halo Reach are the ones I've played and they are great first person shooters!

Dead Space: 1 & 2 are both good games. Second one has two disks!!(for X-box 360) Little over 6 GB on each disk. Lot of graphics and effects in the game!
Rome Total War: Great Strategy game, great thing to pass the time.
Battlefield Bad Co.: Only played the first one a bit, and best part of it is the amount of destruction that can actually be done to buildings and the surroundings!

Gears of War: First & Second games both have good campaigns and are fun to play. and you got to love the Lancer!, I mean, who wouldn't want a chainsaw on their gun?? and Gears of War 3 looks very nice!

Many other games as well that aren't there, including; Dragon Age, Fable, and Borderlands.
