Disagree, in the sense that it has a historical use and development. It may have changed over time, and people may disagree about it, but I think we generally have a sense that AAA games bring clout to a system...they are considered good games AND they sell a lot.
Now. STARCRAFT MADE UP THE IDEA THAT AAA MEANS 90% ON METACRITIC. HE DID IT BECAUSE AT THE TIME 360, WHICH LAUNCHED A YEAR BEFORE PS3, HAD A MUCH MORE LOPSIDED ADVANTAGE THAN IT DOES NOW IN 90% RATED GAMES. It will matter little because PS3 will end up with more 90% rated games than 360, period. Toss out the online games and recognize that 360 has a number of lucky barely-hanging-in-with-a-90-flat games right now, and its nearly even already, despite the fact that PS3 has had so much less time to put out 90% rated games.
Whilst I did not invent the AAA means > or = 90% on Metacritic concept, I appreciate the fact that you consider me so notorious.
I just dropped by to point out that 17 90%+ games to 7 90%+ games does not equal "nearly even."
starcraft - Playing Games = FUN, Talking about Games = SERIOUS
