Luckily I had three or four friends who owned N64s, so for me it was almost as if I owned them. I beat Mario 64, and played the hell out of Goldeneye. Same with SNES, I had enough friends that I never felt like I needed one, especially being a kid in the height of the "Rental era" in the 1990s, I played so much of the library.
The Sega Saturn controller was phenomenal. It fit solidly in your hands, had a 6-button fighter configuration plus additional bumpers for games that needed them. I think the main thing that made the PS1 Dual Shock Twin-Analog controller become the standard instead of this was the dual analog. It was a weird novelty when it came out, but the Saturn didn't last long enough to see the day when it became increasingly standard. The Dreamcast controller is basically the Saturn analog pad that came with Nights Into Dreams, but frankly it isn't very good because of the hard plastic which cuts your thumbs. I think thats one of the few things the Dreamcast has against it. The layout is fine, but the d-pad and single analog stick were poorly made. The DC does have a huge arcade stick though, the one caveat being that it's ugly as sin. The Genesis arcade stick is so much sexier in appearance, and the only arcade stick with a rubber area to rest your wrist.
