And the best way to do that may be to follow in Mario and Sonic at the Olympic Games' footsteps. That original game has already built a strong framework to build on, so all Nintendo has to do is make sure that it can deliver another riveting adventure. Instead of focusing the story on the Mushroom Kingdom, the next Mario-centric RPG should be an epic crossover between gaming mascots. While one of the easiest ways to capitalize on this would be with a Super Mario RPG sequel, Nintendo should actually consider exploring a completely different concept.
