I actually wish Rest's behavior from "Smash 64" and "Smash Melee" would return. It doesn't have to be exactly like those two games, but I at least want the knockback to be similar to those two games. The vertical knockback from "Smash Brawl" and "Smash 4" is bad in my opinion.
In any case, if that instant stock-taken idea (Star KOs/Screen KOs only) is somehow implemented in "Smash Ultimate", I'll gladly accept it, even if it's not perfect. In fact, I'll gladly use any mod (or any GameShark/Game Genie code) that makes top KOs only Star KOs/Screen KOs occurring. Usually, I'm against these, but I'll gladly make an exception. I just want consistency for the top KOs.
I have tried to look past the top KO randomness in "Smash 4" over the years, but I'm so annoyed by the randomness that it's literally become unenjoyable for me now.
So I'm honestly hoping "Smash Ultimate" will change that and will truly be the ultimate "Smash" game. No random elements (tripping from "Smash Brawl" and top KO RNG from "Smash 4"), all consistency. And if things actually go right for competitiveness...in my view, the order would be "Smash 64", then "Smash Melee", then "Smash Ultimate", from beginning to end ("Smash Brawl" and "Smash 4" don't exist to me; no offense to the others).
