I've been wondering if anyone on this forum plays platform fighters competitively.
My favorite is definitely Rivals of Aether. It kind of feels like a competitively-oriented SSBM, but with no shield or grab, being replaced with a parrying system. When one player parries another player's attack successfully, the attacking player is stunned so that the defending player can get a follow-up. There's a lot of other intricacies, but that's the biggest difference (aside from the aesthetic choices and the fact that Rivals has a much more balanced roster. . . no Fox McClouds, Meta Knights or Bayonettas here!)
