The internet shitting a brick about an indie darling? Unlikely.
If the term had meaning then it would be defined. It's like calling a game "pretty" or "innovative". There's not much beyond opinion on it. Many have said it's based on money, but how much and from what? Money spent or money taken? Can Indie titles be AAA or only titles made by publishers? Can a phone game be AAA? Is it based on review scores?
Blockbuster is defined by the takings. Which would mean for a direct translation AAA games would include the likes of:
Minecraft, Wii Play, Nintendogs, Wii Fit (in fact a lot of Nintendo games), Angry Birds, League of Legends etc.
Which does highlight a minor issue in the "blockbuster" stuff in that blockbuster is based on the cinema takings, games don't have the two-stage life cycle of films. Movies don't also tend to show the film for free, with optional scenes or new outfits for the actors purchasable as you watch. So it's a pretty hard analogy to directly translate to gaming without skipping a pretty hefty amount of non-console games. Though I would imagine for many people they wouldn't mind that since they probably might not consider anything out of the non-indie, console only, non-F2P spectrum to be able to be "AAA". Which this wouldn't at all be related to the fact console games from top publishers tend to have those top marketing budgets with their "gameplay" trailers for their must-have "AAA" games.
