Best Xbox 360 Exclusive you have played?

For me it has to Be 100% Fable 2...I just got this game yesterday and it is amazing i never really liked RPG's but since i played this i think im going to buy more!
In second place Gears Of War 2 just play the game you will see why!Best Xbox 360 Exclusive you have played?
Either Mass Effect of GTA4 DLCBest Xbox 360 Exclusive you have played?
Forza motorsport 3.
For me, it's a tie between ''Gears of War'' %26 ''Gears of War 2''. I'm not much of a multi-player fan, so haven't experienced too much of that aspect of the game. But for me, the single player aspect of both of these games was so much fun, and I've played %26 beat them both so many times. Great games!!! Other then that, guess I've gotta go with ''GTAIV : Episodes From Liberty City''. I've only completed TLAD so far, but am part way through TBoGT. Both are fantastic games imo.
Gears of War series and Forza 3. Third place will go to Left 4 Dead 2.
Halo 3
Forza 3. Although Gears of War 2 was pretty epic.
I didn't like Gears of War 2 at all. I never liked the first Fable, but I'm going to give it a try anyways.Well I guess it might be like ummmm Forza 3.
Until Tales of Vesperia is officially announced/released on another console in the States, it will remain my favorite 360 ''exclusive.''
Gears 2 and Forza 3 are definitely some of them.
Best is Mass EffectWorst is Halo 1,2,3 %26 ODST
Forza 3 for me
I don't own many 360 games, but from what I have I would say Halo 3 and Gears of War 2 are the best exclusives.
Mass Effect (though you can play it on PC now), and Gears of War 2.
Halo 3 via Xbox Live with all the roommates (everyone on their own console, of course)! Epic multiplayer in to the wee hours of the morning.
Gears of War 2
Halo 3, and Forza 2. But I'll got ODST and Forza 3 soon, so I guess thay'll become my new favorites :D
Forza 3



Gears of War and Call of Duty 2 are up there as well.
Am I the only one who liked Kameo? I think that game is very under rated. It was the first 360 game I bought and was very fun.
Episodes from liberty city hands down.
