I do not know if you have seen this video but it absolutely nails all my feelings regarding the single player experiences of SSB4. It just sucks.
Every thing feels like multi man melee/brawl which were the modes I wouldn't touch unless I wanted to unlock Falco. And Smash Tour is terrible.
I hope they bring better modes to the 1-P experience in 5mash, because to me even SSB64 was better than Sm4sh when played alone.
And I hope they bring back some of the sound effects from SSB64 and SSBM. They were so satisfying.
All I wanted:
Classic Mode from Melee
Adventure Mode from Brawl
Events from 4
Break the Targets and Board the Plataforms from 64
Orders from 4
All Star from Brawl
Boss Battles from Brawl
