The game Summer Olympics was the best, I was great at the diving. The good old days of nearly breaking your hands and getting blisters from the video games ( I am sure they do today as well, but have no clue).
4-player Decathlon on the Atari 2600 was the ultimate party game. It usually ended in hysteria during the final 1500m race - multiple abandons and a gang-up on the remaining player to prevent him from reaching the finish line.
