the amount of moons in the game is good. it's probably the mario game with the most collectibles, whether it's stars, shines or moons. there are a few things i wouldve wanted tho, and maybe we could get them in odyssey 2 if it ever happens.
-some more outfits. i love the references, they're really cool and some of them are so obscure that even i didnt know about them. however there are some costumes i wouldve liked to see, like tennis mario from mario tennis aces. im honestly surprised it wasnt added in an update. they also couldve added some other obscure references, and i hope they do so in odyssey 2.
-yeah we have a decent amount of kingdoms, but some would've been nice to see, like delfino plaza, which is visible on the globe (though i think we all know this by now), maybe an actual volcano level. yeah the luncheon kingdom exists, but a lava level that LOOKS like a lava level more would be cool. finally, THE RUINED KINGDOM! why, just why is it so little. this kingdom needs to return in odyssey 2, but i just wish it was as big as kingdoms like the sand or metro kingdom. it would be a cool haunted level. i guess we could also see a bigger cloud kingdom.
