What would you replace the Mario and Sonic series with? (You can have a unpopular opinion, so no yelling at others for their opinion... In fact... what I might suggest might be an unpopular opinion) Instead of Mario and sonic competing at the Olympics, characters from different series, maybe even indie games, come over (like smash bros.) and compete in some destruction derby and banger racing in tracks from each of the worlds with some weapons to use the characters abilities and powerups, basically destruction derby and Wreckfest meets smash bros. with a little bit of Mario kart. Maybe even have some alpha and battlefield morph stuff with track morphs like: race oval, crash alley, figure 8, etc.
