With all the "this isn't just a Melee clone" stuff people talk about, it's weird how if you go to the page and read about the characters, many of them start with "X character's Melee self has been restored".
I don't know why this makes me wrinkle my nose; I liked Melee! I guess I'm just put off by the repeated intimation that Brawl was inferior when I played so much Brawl and had so much fun with it in multiplayer. I just never reallly got to play much Melee.
I have so much respect and admiration for what these guys were able to accomplish and I am really looking forward to trying this out!
The thing is, while Brawl is by all respects an excellent game, it isn't an excellent competitive game. A lot of the depth that Melee had, intentionally or not, was thrown out in Brawl in favor of more random elements and more same-y characters in terms of control.
While Project M definitely isn't just a Melee clone, it starts by taking Melee's top-tier characters, typically the ones with the most options and deepest gameplay, and restoring them to Melee standards. Then it takes all the other characters and brings them up to that standard by adding unique elements to their gameplay and overall just making them all better characters.
What results is a brilliant game that is both the most competitive-friendly of any Smash Bros. but also has a lot of fun things for people with less concern for competitive play to try out. It's great, and I hope you enjoy it!
