I have some great memories of playing "Breakout" with my grandmother, on a 2600. Kind of pong like..

You hit the ball up, it destroy blocks, and you hit the ball again. Progressively, it gets faster/harder. If you do it right, the ball can get stuck "above the bricks", and it destroys a bunch of bricks for you without you having to do anything.

I remember the first time that happened to us, my grandmother just about lost it. She got SO excited! "LOOK!! LOOK!!" She was in her sixties and as excited as anything that we'd figured something out.

Good times.
