God.
This thread made me dig out my N64 from the garage.
So many obscure games. Holy shit.
This game was fucking TOUGH AS SHIT from what I remember.
This game was great. It was basically Mario Kart, but you could upgrade and modify your snowboard (gokart), and it actually followed a (strange, but funny) storyline based on which character you played.
This game. God damn. I'd spend HOURS playing with the rollercoaster. There were so many things in this game that blew my mind when I was little.
This one was your usual platformer. Nothing really special about the gameplay.
It was the Gecko. The fucking Gecko. All the obscure references and jokes he'd make I never understood until I was older.
