I'm 6-7. I'm at my grandparents house. He's got one of those old-timey Pong consoles that you plug into the TV; it had like 5-6 different 'sport' modes (Tennis, Squash etc etc), but ultimately it was still a few pixels moving up and down or maybe left and right.
I don't remember what the game was called, but I played it from a diskette on DOS, if I remember correctly. You were controlling a sort of space ship and jumping on different platforms while continuously moving forward. I loved it. But I don't remember what it was called so I can't look it up any more.
We also had some sort of maze game and Commander Keen. But I sucked at Commander Keen, so I never got past the first level.
