The 3 N64 games and the pokemon for gameboy were the main big ones when I was younger. Zelda took ages and was the best game by far back then (even went back to play it recently). Pokemon the first games was really popular in schools in 1999-2000. I was the first in my school to finsh the pokemon game (yes iam proud of that lol) because no one could figure out to put the rock in the hole in that cave before the main league place lol
