Super Pong! It had two knobs and a switch where you could chose one of about 4 options one brother gave it to the family for xmas. Pong tennis, doubles, one where it reversed and you catch the ball, and I think a solo. I was pretty little but it was cool, but a pain to switch the TV over too.
Later it was my friends Odyssey 2, and we got a Atari 2600 from Sears. It came with 'Combat' and my little bro and me would play tanks, jets, and biplanes often.
