I played a lot of Mario tennis / golf and the normal NFL games but my all time favorite was
Town & Country Surf Designs: Wood & Water Rage For the NES
I would spend hours getting the surfing gorilla up on top of the wave and just stay there. Also I think it was the 1st game with skating in it. Was fun and I was the only one who had it.
Winner. I rented that game when I was a kid and didn't know how to play it.
