Mario Kart: Double Dash!!
The staff wanted to let people play online but the technology was not good enough for that yet. They also wanted to do something with a Game Boy Advance connection for this game, but they decided Double Dash!! did not fit anything like that. They wanted to make sure the really good plaers and the not-so-good players were all able to have fun with this game, so they took out things like not slipping when you hit a banana.
