Super Mario Odyssey has been extremely successful on the Switch and sets Nintendo up perfectly to capitalize on its success by reviving Mario sports games. Whether it be soccer, tennis, or even volleyball (part of what makes Mario Party 5 so great), the sports games featuring Mario have been a tremendous hit with fans.
Super Mario Strikers nailed gameplay with easy-to-learn controls, simplified rules, and exciting action. If the series came back with even more playable characters, in addition to stats more specific than "balanced, playmaker, or defender," the game would be an instant hit. The "play anywhere" nature of the Switch would make the game a great candidate for local multiplayer, though it might have to contend with Rocket League nowadays.
