GBC was my first console. I got an N64 later on, but I wasn't allowed to bring it to my moms, so I didn't get to play it as much.
On the GBC, my favorite game was Pokemon Silver (though it would've been Pokemon Red when I first got it), on the N64 it was Ocarina of Time. Played both of those so much.
My mom would also occasionally rent a SNES usually with one of the Donkey Kong Country games or Bubsy so I have a lot of nostalgia for those games as well. I got my own SNES later, after the GBC and N64 though. I still don't own my childhood favorite SNES games, well except for Super Mario World. SNES games are so expensive nowadays.
I played NES a few times growing up but it was so early in my life that I didn't really understand games yet and don't have any clear memories of playing it, or much nostalgia for it, and the NES quickly became old news when the SNES and N64 came along.
