I am disappointed with the game.
It lacks content. The stage number is smaller than brawl!
The single player experience is crap. You can unlock every character and stage within 3 hours. (I did that and did not look for walkthrough or whatever at all) Even tho i have not played smash or any other fighting game in years. There is no challenge whatsoever.
The only thing left is some of the challenges but since there is nothing I can unlock why do them? (well and trophies but this again does not need any skill it just needs time)
Brawl was much better in every single thing minus the character balance. I love how Smash 3DS plays. (the controls suck tho)
