Oh fuck yes yes! I hope to god this is true, All-stars was a great first run at it and helped establish some mechanics, test out an online infrastructure and create some interesting character move sets. Everything else was lacking.
A sequel that brings a professional presentation (menu's, stories, UI, ect) and loads it w/ extra content (not just icons/minions) could be an amazing thing. Especially for PS4! I hope this works out!
Honestly, they probably need a game designer even more than a UI designer.
The instant kill super mechanic is a dumb gamplay mechanic and level 3's being guaranteed is a fucking atrocious idea. I played 4 or 5 rounds with some friends and we all pretty much universally agreed to go play smash bros instead for the rest of the night.
Different experiences. I also had friends over and we played All-Stars, went to Smash and then back to All-stars. Smash Bro's is a much more relaxed, fan, stress free game. If you lose in Smash you don't feel all that responsible (accidental deaths happen), in Allstars if you lose you know your skills were lacking. While I do think Smash is more crazy fun, Allstars is much more rewarding (like a traditional fighting game is). I think a sequel would benefit from a more relaxed party mode (stage deaths, health bars ect) and also having the traditional ranked mode (as it is now). So it could be played serious or just for fun.
