Question we have to think of, are we doing the best of '00-'09 (because '10 was out of the list) vs. each other, or are we doing just best overalls? And are they again, overall, or are we talking about the best of the community? Also, would we count the figures of time out vs. copies sold into the factor? If so, it'd be 2011 by the time THAT one came out. You can't do total copies overall because if a game since 2001 sold 1.3 million and a 2009 sold .7 million, the '09 game may have been released in Oct. and the numbers be different per average
A true top 10 list for the decade would take about 6 months to get all the votes in, compile the data, ect. Plus if you did add in the copies sold vs. time they've been out, it would take a LONG time...though I forgot to ask, what about God of War? Was that game nothing to the video game world? Was the combat and story not epic? And even Batman Arkuhm Asylum was a game with maybe not the best story, but I want to keep playing the game after beating it, the secrets are challenging, the combat felt natural and easy to pick up but still takes skill the master and the gadgets are Batmantastic
I think IGN failed hard, but I also think it was a small group who all had similar intrests and that's how it got to what it was. Another mention I remembered, the Prince of Persia Sands of Time Trilogy
Another question to make this longer, do franchises of the decade deserve credit? The SoT trilogy was great, but the games on their own may not add up to their true might. God of War was good on it's own, but even stronger as a pairing, and with the 3rd installment coming out, will hopefully be stronger still
