that's tough... I'd have to say mine jumped back and forth early on between Mario kart 64, star ocean second story, and rampage world tour, but when banjo kazooie came out that became my solid favorite, tying only with the sequel banjo tooie.

super mario world and yoshi's island

Earliest favorite?
Super Mario World and Pokemon Yellow

Paper Mario

I think mine was Donkey Kong Country followed by Banjo-Tooie

^ yeah donkey kong country does hit the list too, but when I was younger I never really got to play it much since the snes was at my cousins house so I don't really count it as 'favorite' since I didn't play it as much as others. Banjo Tooie though I have played so many times throughout my life ugh god I love that *crag*ing game

Yeah actually I consider my copy of Banjo-Tooie a prized possession. It's just such an awesome, well done game, and really shows what the N64 can do.

pokemon red, and ocarina of time
funny thing i dislike both of those games now

Oh boy. There's a few candidates, the most likely being Lego Racers on PC. I was also pretty fond of some obscure Magic Schoolbus, Thomas the Tank Engine and Rugrats games around the same time, but I've never been able to pick a favourite. Bear in mind, I didn't have anything other than a PC for several years so I had little experience in console games.

Super Mario Bros, Duck Hunt

Oh yeah I had Mario 64 and Paper Mario on an emulator, those were pretty good too

Mario 64 and then Donkey Kong Country

Oh yeah I forgot about Lego Island, I had that one for a long time. I can't really remember when I got it or what else I had back then, though. I just know I liked it.

Probably Adventure Island II, followed by Bomberman 64.

Pretty much any mario game, my obsession with mario was borderline autistic at those ages.

sonic 3 followed by 2
