Weekends playing Mario Kart 64 with my cousins are my best Nintendo memory. On friday we'd go to the store which had a gumball machine. Inside the machine were slips that had prizes. You could win stuff like a Pizza, some Pop, even cash prizes. We'd go in with $5 worth of quarters, and walk out with a large pizza, a 12 pack of pop, some chips and a crapton of gumballs.
We'd play Mario Kart 64 all weekend long. Best part was when we were playing battle mode and my cousin was a bomb. He was chasing me and almost caught me. I ended up getting a starman before he hit me and he disappeared! He was furious and everyone was laughing at him. Some of the best Nintendo weekends of my life.
