I don't have a proper definition (pun intended) but I'll try to explain why I think that Sakurai's mindset doesn't feel right to me.
His "everybody should win regardless of skill level" approach just doesn't work, he dumbed down Smash4 as much as possible to avoid that advanced players can crush casuals with wavecheating and lame canceling, but this idea is just flawed to beginn with, even if the game would be only one button, the more advanced player would still win.
So why not throw this mindset out off the window and make something like Melee?
Note, it doesn't have to be Melee 2.0, not the slightest.
"Easy to start but hard to master", for me personally that would be a great design formula, give the players the choice to choose between just playing and having fun or go serious and give them some advanced stuff to strive for.
To make it clear, I don't want the next Smash game to be made just for competition but on the other hand I don't want it to be dumbed down.
Why not just a healthy middleground?
But with Sakurai this will forever be a dream :Biblethump:
Let me also mention that if you patched out all the tech that Melee has and Brawl doesn't, Melee would be about as slow as Brawl. It's been tested before.
No offence, I don't understand why you wrote this sentence?
