I'd make 20 million more spinoffs to release in the following 3 years, collect the money, and retire to a mansion in California, thereby marking the end of the Mario Franchise.
I'd also cancel upcoming games, such as Super Paper Mario, Mario Hoops 3-on-3, and Mario vs. Donkey Kong 2: March of the Minis. When asked why, I'd simply reply " I felt they were getting in the way of my vision. " Once people rebel, I'd simply sell Mario clothing, such as Mario gloves, Mario boots, and Mario overalls. ( Truth is, people actually buy that stuff. )
