1. Make a game trilogy where Ludwig Von Koopa makes a dream machine, and Bowser uses it on Mario. Bowser releases Wart into the Mushroom World. Peach rescues Mario. In the second game, in which Luigi would get an actual starring role, Wart kidnaps Daisy in Sarasaland, and Luigi saves Daisy. Third game, a Mario & Luigi-esque RPG, Bowser and Wart team up and capture Peach and Daisy. It's up to the Super Mario Bros. to, once again, save the princesses.
2. Limit the Mario Party games to just one or two games per console generation.
3. Ask Sakurai to include the Baby Mario Bros. in SSBB.
