Brilliant idea. Great stuff, Dubrow!
Are you going by North American release date btw?
P.S. What's the difference between popularity and sales?
A couple of suggestions from what I can see:
I think Crash Bandicoot should be ahead of Super Mario RPG. Even though Mario RPG takes acclaim, Crash takes popularity (6.82mil vs 2.14mil) and impact (Crash sold was the first non-Japanese game to achieve commercial success in Japan and became Sony's mascot because of its success, before the mascot era died out).
For 2002: I'd say SoulCalibur II should be on here, SM Sunshine and Eternal Darkness look too high and Vice City should be #2 I reckon, possibly even #1.
2004 is probably the list I disagree with most. The top 5 is fine, but the 2nd half looks a bit weak. I'd put Katamari Damacy in there at #6 and would put Paper Mario well before MP2, Fable or Pikmin 2.
Think Portal should definitely be ahead of Rock Band and Portal 2 ahead of Arkham City.
For 2012 I'd say something like this off the top of my head:
1. The Walking Dead
4. Mass Effect 3
5. Bordelands 2
6. Halo 4
7. XCOM: Enemy Unknown
8. Far Cry 3
9. Hotline Miami
10. Assassin's Creed III
