My list goes like this:
1. Uncharted 2
2. God of War 3
3. Killzone 2
4. Heavy Rain
5. Metal Gear Solid 4
6. Flower
7. Folklore
8. The Elder Scrolls: Oblivion
9. Bioshock
10. Uncharted: Drake's Fortune
In about a year, I'm betting the list will probably drastically change to something like this:
1. Gran Turismo 5
2. Killzone 3
3. Uncharted 2
4. Infamous 2
5. God of War 3
6. Resistance 3 (I don't know, I have a feeling Insomniac might try to impress)
7. The Last Guardian
8. Dead Space 2
9. Little Big Planet 2
10. Naruto Ultimate Ninja Storm 2
Bet with Conegamer and AussieGecko that the PS3 will have more exclusives in 2011 than the Wii or 360... or something.
