Shouldn't this just be merged with New Super Mario Bros. Wii? After all, keeping game nodes in the game article is the case for Mario Party: Star Rush's article (as is even said in its feature nomination). Toadette icon CTTT.pngArchivistToadettefont.png(T|C) 16:13, 3 June 2018 (EDT)

I would say so. Game modes are usually only split if there is a lot of extra content, such as Battle Mode, and multiple modes larger than this one, such as Subspace Emissary, Mario vs. Luigi, and the Super Mario Run modes, are kept on the main game article. I do not feel this mode has enough content to warrant its own page. --FlameChompNSMBW.pngTheFlameChomp (talk) 16:26, 3 June 2018 (EDT)
Yeah, that might be right... I tought that it deserves a page because Coin Battle has a page. BlueYoshiYoshisStory.png Yoshi Egg 1990 Red-yoshi-with-umbrella.jpg
That's probably because Coin Battle appears in more than one game. We can always assess whether that needs its own article some other time. Toadette icon CTTT.pngArchivistToadettefont.png(T|C) 17:08, 3 June 2018 (EDT)
