If were speaking of our personal opinion on a game, I don't put games in terms of AAA. I'm just aware that I want it really badly.

If we're speaking in general terms to get a point across, like "so and so console has so and so more AAA games than so and so console #2", then I consider a game 90%+ on gamerankings and/or metacritic to define the status and don't take sales into the equation.  

Being 88+ on metacritic is what a AAA title is considered for me.

Games that are really good...

It has nothing to do with what other people think or performance of the game. The mass market can all rate a game 1 out of 100. Just as long as the person playing it enjoyed it extremely. I never played a ratchet and clank game until Future. I was fascinated with it and believe it was AAA. Uncharted was AAA to me.

Halo(1 and 2) I have tried playing through and can't complete the damn things. I find them dull and boring.

Gears I find lacks any type of story and doesn't influence me to finish it. (I did though in Co-op)

Those games for me were not AAA

Nintendo games... I haven't played the Zelda or Mario games but SSBB I have played. I find that game not so much fun by yourself. It is only fun playing with your friends in my experience. I would not define it AAA. Don't get me wrong I really enjoy it... only in certain circumstances though. I didn't enjoy NMH. They went the artistic route for that game and I like those type of games... but I don't know it just didn't rub me the right way... Maybe it was the motorcycle... maybe it was the pixles...

something thats enoyable by everyone, and keeps on bringing the fun.

ratchet and clank, jak and daxter, super smash bros,

a game that makes you feel good inside

That sums it up. Any game can be AAA for anybody depending the compatibility. I almost didn't recognize you. Haha trying to hide your identity?

a good story and great replay value

AAA title is a blockbuster game that everyone buys, it obtains a review score of 85% or higher and the game sells in excess of 2 million copies.
