Wonder if there'll be online multiplayer
From what we’ve seen about Super Mario Bros. Wonder, it looks like another 2D side-scrolling Mario game that focuses on local multiplayer. That’s all kinds of fantastic, but there’s surely some people out there who’d like to take that multiplayer online.
While nothing has been announced about any sort of online play at this point, it seems like Super Mario Bros. Wonder will indeed have some kind of online functionality. The official info page for Super Mario Bros. Wonder on Nintendo’s Japanese website includes a line stating that “details of online play will be announced at a later date.”
Of course, this mention will no doubt have many hoping that multiplayer will be a local and online affair, but we honestly don’t know at this point. At the very least, it does appear the game will offer some sort of online component. Now we’ll just have to sit back, cross our fingers and toes, and hope Nintendo reveals the type of online play most would want.
