I would say definitely have a look at the Wii version then. The single player part is ace.
Yeah, I did like that. It reminded me of Streets of Rage in co-op, or the closest we've got to it in years.
Equally I like Smash Run on the 3DS. It's become my go-to mode because it's great at seeing+getting lots of content and is also pretty good in multiplayer.
My copy of Smash just got dispatched today so I'm hoping I'll get it tomorrow 🙂 along with all the goodies I ordered for it; Official Smash Bros GC controller, PDP GC-style classic controller, Hori GC-style classic controller, Pikachu and Marth Amiibos.
