So the biggest feature for USUM is travelling to few Ultra Worlds which also most likely will have version exclusives so less than 10 worlds to visit in each game. Not to mention they all seem as "explorable" as Nihilego's world. And thats supposed to be the "big thing" for post game?

Aside from that Photo club, mantine minigame, few z-moves and O.M.G. Few new UB legends to catch post game and virtually never use them outside of online

Are you fucking kidding me?
