Space invaders but you’re the invaders would be fun. And I have to assume it’s already been done

agree there are probably a bunch that would be fun. packman, play as a ghost and need to multi task to get all the ghosts in a spot to trap pacman

donkey kong, play as donkey and try to time barrel throws to hit mario

galaga, play as the fleet, control left right of the whole fleet and have the 3-4 different "attacks" you could send out.
