RE5, AC and COD WAW are "AAA", because they had enormous development and advertising budgets - and that's all "AAA" means

I would classify Dead Space, Infamous(maybe this one is more of an "A"-lvl production ), Uncharted, PoP, Resistance 1/2 and the Sport games as "AA", because they had big budgets, but not on the same level as the 3 others.

AAA generally refers to a game that recieves a 90% or better on metacritic

What a game nees to get AAA? Either:

High Budget
High Ratings (above 90% metacritic)
Large marketing campaign (doesn't count for Wii games. The Wii is a toy)

For me its, over 90 on average, reaching 5m in sales in total, and the game keeps you coming back even long after you bought it, possibly affecting your gaming habits and thinking in real life.

So none of those games are AAA in my opinion. The closest are RE5, COD WAW.

What determines if a title is AAA?

Me.


No kidding. I think the most commonly accepted definition is 90%+ on Metacritic. But a game doesn't need to be AAA to be awesome.

I would definitely go with the latter over the former, though neither are really good definitions of AAA.

Going with the former, Too Human is a AAA title while Okami is not. 

A triple A game usually has the following features

1. High budget

2. Mostly favored reviews (around 85% or more)

3. Sell alot of copies (usually at least 1 million)

4. Is played alot even months later like Halo and COD (this only applies to multiplayer games as they are usually the only ones that can be tracked like that)

So if a game can be awesome without being rated over 90% on metacritic, isn't your sig pointless starcraft?

But then he can't make the 360 look better than the other consoles!

AAA roughly refers to the budget of the game as some already pointed out.
