Mario platformers for home consoles should have online multiplayer for now on if they already have local multiplayer. Smash Bros. for Wii U is a fighting game that runs on a 60 fps with 1080p resolution and it plays relatively well online. NSMBU and 3D World has 60 fps as well but is only 720p. There is no excuse for the next multiplayer Mario game on home console to lack online multiplayer. They can make new levels to compensate the lag or allow random match-ups to connect only if connection is decent. I do like the ghost data from 3D World and wish for that to continue in the 2D games.
I wouldn't boycott or look down at future NSMB or 3D World games that have no online multiplayer but I think it would show how unambitious and stubborn the developers are for not trying to include it. If it takes too long to have a working online multiplayer mode, they can always promise to have a free software update for it a month or so after release. With how buggy some online modes are this gen, customers will probably be used to waiting for decent online now. Plus, Mario games always have great single player so people have something to play with while they wait.
Do you think its time for future Mario games to have online multiplayer if they're from the NSMB or 3D World series?
