My first system was the Sega Megadrive, and I got it when I was 3 or 4. I spent hours on that thing playing mostly Sonic and Street Fighter. I can still remember beating my dad on Street Fighter even now.
GameCube is only a generation old. The NES on the other hand is ancient and I think I only had one cartridge for it which was the original Mario and duck hunt. The SNES was more fun thought.
