Still got to be a main game at CEOtaku for like, every single year. It has had and continues to have some of the best netcode available thanks to CCCaster. Type Lumina is absolutely a "main" anime game rn. It's on the primary Evo roster, going to likely be on the Combo Breaker main stage, has main event slot at basically every major that's gonna happen this year.
It's on steam lelDid it ever even get an English release, outside of fan translations?
I think you really underestimate how beloved Melty has been for all this time. Almost every single anime player has some character in Melty they can play, it's kinda nuts. Probably the most ubiquitous anime fighter of them all thanks to its longevity legacy + netcode. I would have never called AACC non-existent outside of jokes, you find Melty setups at literally every major.
