Yup. I'm loyal to Nintendo. Bought all their handhelds, all their consoles, all their pokemons, all their Zeldas, all their Mario Karts and platformers, all smashes, and so on, since N64/GBC
I'm not loyal to Nintendo, I'm loyal to Miyamoto/Sakurai. I know that if I buy other consoles, I'll regret it, because I'll want Zelda. Thereby, I'll buy the Nintendo console, and only play that. Therefore, as long as Miyamoto/Sakurai, and a few others, don't die all at once - sure, I'm as loyal as they get.
