The initial trailer was pretty poor.
The biggest problems were the fact the sound design was poor, the models were underdeveloped and it was incredibly derivative from Melee characters.
There is a difference between inspiration and just reusing again and most people from the initial trailer thought it was that.
Compare this with rivals of aether, rivals is very very much smash inspired, however they characters still stand out on their own. Zetterburn is very much spacie inspired, more so Wolf, but he still stands on his own and has a move set made to be him and not mimic another characters. A fire lion that has his own history of leading a county and being manipulated with a side story with a brother who is a master of shadows age smoke.
Compared to Kidd from icons character that is a stand in for fox more or less. He literally has the same move set and animations. His name is a reference to mango and he is a space animal.
Kidd isn’t the only design problem, there are a number of characters who are very clearly taking heavy inspiration from Melee. There is a Marth, a Falcon a Ganon, etc.
This is really what needs to be fixed and i’ll Be checking out the closed beta but from the gameplay and direction I don’t have great impressions of it. PM could get away with it because it was a mod going for that, this though?
Earth Romancer is a new up and coming one that looks pretty solid. It has inspiration as well but it still looks like it has a new spin on it with it’s own characters and style changes.
Rivals of Aether is how to be smash inspired but also stand on it’s own, this needs work on design, along with sound and art.
I wish for it to improve but I do think there is valid Critism even if there are devs on the team I like.
