Smash Journeyman
I hope you know that the casual fanbase will buy the game no matter what, if it says Smash Bros on it, the casual fanbase will buy it, it is the competitive audience that is keeping the game alive and that is the audience smash should appeal too. Why do you think Melee was so popular because it was a game both audiences can play and Brawl AND Smash4 (yes I know I said it) don't appeal to those audiences equally (Sure there is competitive audiences for those games but they (Brawl) don't last as long as Melee, that is why Brawl is dead because it did not appeal to competitive audiences).If Smash Bros. we're to lose its casual appeal in favour of something similar to Melee or Project M, that would be the day I stop playing Smash Bros.
Think about it that way.
Read aboveMy point is, if Smash ever becomes this, then Smash will die for many of us.
