Always curious what other gamers think are the very best games of the decade?, as since it's always so subjective, it's interesting to trade this info. It came up in my mind today after reading Paste Magazine and seeing they thought "Portal" was the very best. What are your top picks? 
 
Here is my current list (which could change tomorrow) Funny they are all recent titles:
5. Fallout 3 
4. Uncharted 2
3. Forza Motorsport 3
2. Mass Effect 2
1. Red Dead Redemption
