this Metacritic round-up of the year's top games and it's pretty obvious that Uncharted 2 is the best. Also, according to math, the PS3 is better than the 360. This isn't us or even Metacritic saying it, people, these are innocent, irrefutable numbers.
In all seriousness, while Metacritic has collected some interesting, worthwhile data in its report, we're not sure what the point is in trying to pick the best system or game of 2009 just going by statistics. We've relied on numbers just to help us organize our annual Game of the Year selection, and even so, just look how much damage they were still capable of.
