Yeah, I'm one of those people.. While Mario games are pretty well polished and fun to just sit down and play. But I see them as more super polished time-waster games, rather than real meat-and-potatoes games. I can't sink my teeth into Mario. There's no compelling plot or character development. Not supposed to be, yes. But Zelda games don't really have that either. Or Metroid. Or Starfox. The games are pretty and they play really well and I was fine playing pointless games as a kid. But as an adult, I require a bit more stimulation for my brain while occupying myself with a game. In that regard I find them childish. Having tried a Paper Mario game recently, I have a hard time believing Nintendo is capable of making anything that mentally stimulates me like I need out of a game. It's much less about the aesthetics for me though, if that's any consolation. Collecting a hundred pokemon or building a town full of furries just doesn't do anything for my adult brain :/
