My feature wishlist for future Mario Games: (might be too much)
- Ability to eat and drink for 3D platformers, Luigi's Mansion, and RPG games to restore health and stamina
- Damageable vehicles for Mario Kart and the ability to fall off when using bikes. Engines can overheat (like ExciteBike), tires and body can break, and fuel can run out
- Wario as a selectable protagonist in Super Mario games, instead of his own games
- Wii Sports-like minigames for Mario Party
- ||Mario & Sonic at the Asian Games (exclusive for Japanese, Chinese and Southeast Asian region)||
