My vote is for Fable II. It is a shame nobody mentioned this game before. The atmosphere is really great.
But it is a question of taste.
- Gears of War2
- Fable II
- LBP
- Fallout 3
- MGS4
- GTA IV
are all great games. If you are into shooters, you go with GoW². Sandbox --> GTA IV, Stealth --> MGS, RPG --> Fable II / Fallout3. So this year GOTY could stand for Genre of the year.
Imagine not having GamePass on your console...
