When crafty boss finishes the multiplayer mod it should be a category, with 2 subcategories, the first would be 2 people playing in singleplayer mode, but working together through the mod, and the second subcategory would be 4 people playing 2 player mode, e.g. 1 person playing Mario and another playing Cappy, working together with another Mario, Cappy pair over the mod

I respectufully disagree
Not everyone has a modded switch

Feels way too niche
