I already have Odyssey and 3D All-Stars on Switch. So that's four 3D Mario games. 3D World always just looked far less ambitious than all the other more open-level 3D Marios.
Is it worth getting when it comes out on Switch or is kinda like a side Mario game that isn't up to quality or scope of all the other 3D Mario games?
Also if you do love it, is it still great just doing one player? Or is it more of a multiplayer game? For example, I got NSMBU:D on Switch and found it just okay one player, but I had a blast the one time I played it two player. Is it more like that or is it a legit quality Mario game even playing alone?
