I've never heard anyone say AAAA before Jim, in this video. Hell, I hardly ever hear people say AAA anymore, unless they're talking about indie games and need a term to distinguish. Jim is screaming at ghosts living rent-free in his head.
ETA: Against my better judgement I watched the video --or at least the 3 and a half minutes I could manage before audibly shouting 'oh shut the fuck up, Jim'-- and it really is mountains out of molehills.
Who gives a fuck what companies think AAA means? It's just a useful term to categorise different scales of games; everything beyond that is you projecting, Jim, you bitter little wretch.
