Wow...the first games I can remember playing are ProAm RC, Dragon Warrior (well mostly just watched my Dad), Mario, etc on nintendo. Winter Games on my old PC. No idea what the PC was, but it was on an actual Floppy Disk (5.25 in), SimFarm on the PC on a 3.5 inch disk. Pitfall on an Atari. Again no idea what atari it was because I was too young to care.
My parents tell me I could get a good way through Mario by the time I was 3 or 4....lol. I've been playing nintendo ever since.
