RIP the fact that their are many mods of this game that make this game even more fun with tons of extra maps but nobody will play them like for example: NSMB: BATTLE R, and Another NSMBV 10 players.
NSMB wonder, Some of the mobile ones, NSMB renewed and lust's 1.8 Duckery (no cussing). So yeah there's a lot of mods that get unoticed by the community
