I remember Winter Games for the Atari 2600. It was a good title for that platform and was fun to play. Had a great time competing with friends in the various events. One of the better games for the 2600.
The key to these Olympic gams was having the right joystick. The Epyx Stick was the best. Played the C64 versions for many many hours. Up to 8 players could compete, so having a bunch of friends over was fun.
