Well, by "critically acclaimed" I was refering to game reviewers in general, and the average of over 90% would be on a site like Metacritic or Gamerankings.

An AAA game is one in which I have deemed to be.

Who cares if a game has a big budget, what matters is the quality of the game so AAA should be given to games that are amazing, regardless of budget or sales.

AAA game, is that game - reason, which makes MANY people to buy or want the system, where that game was released.

Thank you. =)

It's the game that everyone wants... whether the game is any good or not it doesn't matter.

AAA is one of the default sets of letters for people too lazy to come up with a decent name along with asdf and qwerty.

An AAA game is a "system seller," plain and simple. Thus far this gen, we've had three (Wii Sports, Halo 3, Super Mario Galaxy), and likely with more to come.

Good question/s.  I'd have to say it's one term that i think has been thrown about a fraction too much as of late.  First i think it's necessary to distiguish between a AAA game and a blockbuster game, another poster game the Spiderman analogy, another example would have to be the Mario Party series.  Blockbuster; yes, AAA; no way.  Can a AAA game be a blockbuster, sure, but the reverse is not necessarily true.  I don't believe sales have to be part of the equation but obviously sales do determine which games we get to see sequels to and this in turn gives rise to what we might call AAA franchsises.  Games that have such a strong heritage that we assume they will be AAA before we even play them.  I would still argue that they are not actually AAA until they receive the official stamp of approval and the necessary critical acclaim.

I LOL'ed

No, a "system seller" is a blockbuster game, not AAA.

The term AAA originally applied to the version of a game in it's release. AAA has nothing to do with sales, but some people started to twisting the meaning  of Triple-A.
