They should have just ported smash run.

I feel that they could've done Smash Tour something better by putting it online.
And make "non-Smash-battle related" challenges (Destroy "X" enemies first; Be the last one standing at Cruel Smash; climb at the top and race to the finish from the 3DS; launch the sandbag further than everyone; collect all the food until you restore back to 0%; KO Ridley/Metal Face; Chase and destroy the Souflee; Destroy more blocks than everyone in Trophy Rush; etc…).

I feel that this would at least make it 10% more acceptable
