Gamboy Colour: Pokemon Yellow.
N64: Pokemon Stadium
Gamecube: Smash Bros Melee
Wii: Smash Bros Brawl
(consoles I bought after I had grown up and they were already old)
Megadrive: Sonic 3 & Knuckles
Mega CD: Sonic CD
Dreamcast: Shenmue 2
Saturn: Panzer Dragoon Saga (This game should be remade. It would fit today's audience much better than the audience of its time)
SNES: Super Mario World
NES: Super Mario Bros 3
The upper consoles, I listed the games that got me to buy them.
The later ones, which I bought way after when I started collecting. I already knew a lot about their libraries. So I listed the first game I bought for the system when I got it because that's what I considered the essential game for the system.
I LOVE ICELAND!
