The game suprisingly doesn't feature any characters (aside from Starliw) or locations that originate from M&L or PM, despite being a crossover of the two series. It doesn't have any of its own unique characters or areas either, there's just Mario characters in a boring-looking Mushroom Kingdom. But the overworld is at least still fun to explore, and I think the game does a good job with the characters it has. There aren't any 2D sections like the Dream World, or Giant battles, and the game doesn't make use gyro/mic/touch controls. But it does have Papercraft battles... They're not really a great part of the game, but I'd say they're more fun to play than Giant battles. And there're the Paper Toad missions, which are mostly just minigames or rounds of Hide'n'Seek around the overworld. Some of them are fun, but others are just annoying. But this game is pretty fun at the least.
