The majority of the AAA/AA projects I've worked on have budgets. I'm struggling to think of a project that didn't have a budget.
> Team Meat is just two people, four if you include the producer and the composer, I would very much assume they knew each other fairly well, but there's no meaningful interpretation of AA where Super Meat Boy is an AA game.
Of course you would expect a small indie team of 2-4 to know each other. I'm saying that once you hit AAA size teams that no longer becomes feasible.
