I think my first video game experience was Pong
It was the earliest Atari model that my mum found in the attic (these things are always in attics). She hooked it up to the T.V. one afternoon with a collection of other early cartridge games, turned it on and left us to it. I think she was after a quiet afternoon, tbh, and it worked stupendously.
Well, up until my sister and I started hitting each other with the joysticks because we hated losing at Pong. Then again, we always had to fight about something. It wasn't a fun afternoon unless we finished off with a game of Sibling Rivalry, and one of us ended the day in tears.
