Great game and lots of playable customised levels from people around the world available on the wii u.
Time will tell and I'd be extremely happy to be proven wrong, but I honestly don't see SMM2 adding anything significant enough to warrant purchasing it for those who own SMM (WiiU) already. I think a massive missed opportunity was not allowing levels being created in the Gameboy/Colour style of games.
Different difficulty modes I think, normal and expert are what I can remember watching one of my favourite streamers play. :)
Always thought of getting this. I watch this on twitch occasionally. The levels seem brutal. Are there any easy levels or are they all as difficult as the ones on twitch?
