Atari is the only 8-bit system I can remember. It doesn't seem like there were a lot of games for it. I had the usual, I think, and a couple of obscure titles that I found in garage sales that wasn't much fun.
I also remember pong. I remember the first time I saw one. I was just out of the military, or on leave, I can't remember, and a friend introduced pong to me in a bar. It was one of those crt tube facing up models that 2 people sat on either side of.
Was the first Nintendo an 8 or 16 bit machine? If it was 8, then I played a lot of games on it.
