@ooignignoktoo if it's something like tetris 99 i feel like it could work pretty well actually. bunch of power ups to stop the competition and you're all racing to pick up people. it would turn a super hectic game into an even more hectic game.
the only downside is that, like with f-zero 99, you're not actually getting a new game in the franchise, it's just a dumb little spin-off which is saddening for hardcore fans.
