Fun Fact: The Japanese version of Excitebike did allow players to save their track designs, using a cassette tape peripheral.
Excitebike was a launch title for the NES. Players controlled a motocross racer in 5-player races or time trials on side-scrolling tracks that were loaded with jumps and obstacles. Players also had to keep tabs of the temperature of their motorcycle's engine, so the game wasn't just about speed and maneuvering.
Excitebike included a level editor, which was pretty advanced and forward-thinking at the time, but the cartridge didn't have battery saves, so players couldn't save their track designs!
