Edit: It should be Miyamoto but can't edit titles....
Sorry if already posted.
Disclaimer: I love Mario Kart and dislike twisted metal but this ammused me.
Apparently when Miyamoto first went to Retro Studios, they were making a car combat game, he said, "Why would you make that? Why would you put a gun on a car?" And they stopped development on the game. So maybe you should answer that question. Why would you put a gun on a car?
Jaffe: You know, honestly, I've been too busy recently trying to figure out why the fuck go-karts shoot banana peels.
