Since we're all sharing bad ideas here, here's mine:
Sega should do a budget Virtua Fighter.
Not Virtua Fighter 6, but a Virtua Fighter Classic. Modern gameplay and animations, but blocky Virtua Fighter 2-style graphics in high resolution with cleaner textures and bright colors (especially the AM2 blue sky).
Play up the nostalgia. Play up the legacy. Sell it for $20 or $30. Optimize it for Switch, but release it on everything.
Goddamn it hire this man Sega
