Which of these four games to buy?: Halo 3, World at War (cod), Gears of War 2,

Fable 2 (I can pick 2)? P.S. I can choose 2 of these games (which is why I chose these games in particular because they are $20). I hear that they are all great games and I want to play them all but in your opinions which should I get?
I'm not saving up my money, I already have Modern Warfare 2 and I don't need to rack out another $60 for one game. I am patient so I can wait. Which of the four games should I get?

COD fersure & Fable 2. Halo is okay, but its at the bottom of my list.

Don't get any of them. Just save up your money to get Modern Warfare 2. Its a great game. If you can't then get Fable 2 or Gears of War 2. Halo 3 and World at War get old in a day.
