You haven't played the trash cleaning side mission. I'm sure any fan of Galaxy hasn't and is actively suppressing that memory. Say what you want about Odyssey's volleyball. It's nowhere near Galaxy's bullshit.
Er, actually @Brawl Mario, I liked the trash ones. They were hard, but I liked them. Also, the volleyball was outrageously hard, unless you play two player, point Mario towards the court, and play just as Cappy. (A friend showed me that)
