I didn't say the N64 wasn't profitable or didn't have 40% (just spitballing, probably less) of the US marketshare for that gen. My point is that Nintendo stopped being one of the big swaggering dicks of the console industry with the SNES, and the only time they managed to get back in the game was by making an underpowered gimmick machine that people forgot they owned after 2 years.
I also think focusing on profits when talking about Nintendo is missing the forest for the trees. Sure, they keep making money (until very recently at least) and have a fuck ton stashed away... what the fuck good is that doing them or you? Not a fucking thing when they cheap out on hardware, don't have a solid launch lineup, are negligent at best or outright hostile at worst towards developing relationships with 3rd parties, and still in the 90's as it regards online play.
Basically, they're not worth admiring because you like pokemanz, playing dress up with dumb fucking animals, or playing mascot brawl 37: button mash prime. This is like stanning for a chick that used to be hot and shits herself now. People can do better.
