I'm firmly in the "N64 controller is great" camp, it's one of my favs. That being said, I have a bias as it's one of the few controllers designed for those of us with three arms.
I'd like to addend my original statement, btw- I will play emulators and roms for shit I have IF I'm chilling with a friend and we want to play random games. That is to say, we pick a system and literally pick a game completely at random from the hundreds or more available roms. It's a quite fun way to play tonnes of games (of varying quality) that we wouldn't otherwise play.
