This is why fighting games will never hit the same amount of popularity they had in the 90's.
People loved fighting games because of their simplicity. Any retard could slap some buttons and do something. And you get two of those retards side by side? Cool, pretty fun. This was all ruined when the turbo autists rolled in with their memorized combo lists and just made the games miserable to play.
Now, every single faggot has those combo-lists, and worse, because of the state gaming is today, have downloaded twelve fucking videos flowcharting exact reactions and timings, down to the FUCKING 60TH OF A SECOND, and thinks they're gonna be the next Justin Wong. So, online play doesn't have that 'two retards slap-fighting and having fun' vibe anymore. It's all sweatlord tryhards doing whatever someone on youtube tells them the champs are doing. And that's not fucking fun. Even MOBA's handle that better, since even when playing against sweaty tryhards, you aren't locked down, unable to press a button for the entire game.
You bring up TFH, and I actually love that game unironically. It's fun and charming, and the story behind it is downright touching. But I don't play it, and could care less about any DLC added. Why? Because playing online is a fucking cancer pit, because no one wants to just have fun anymore. Edit: And as you said, their story made is taking a literal decade.
Fuck you Steve Jobs, you killed gaming too. Rot in hell.
