FTFY. While Smash 4 has a thriving scene now, it's all downhill from here after EVO. It's living on borrowed time, & like I said earlier, I can't see any scenario where Smash 4 lasts longer than Melee in the FGC.Melee is the only truly competitive game they have as it is right now. Splatoon could become one, if they tweaked it a bit (added a competitive mode, with custom lobby setup).
It also would be a lot easier with a better account system, where you could log into any Wii U and keep your personal setup.
And once again I give the disclaimer that I play both Smash 4 & Melee competitively (though a bit more on the Smash 4 side).
