Something I think is really interesting about Knuckle Fighter is people had been digitizing themselves since it's early days, usually to recreate characters they couldn't get sprites for.
Over time people added more tricks to it, so there's a spectrum of really rough digitized stuff to people full-on animating themselves and drawing extra frames.
I'd never seen smear frames on a real person prior.
Strive's soundtrack is incredible. I don't care who hates it, I appreciate Daisuke (the god) for being so experimental with it instead of just trying to make "fighting game music" or "Guilty Gear music" at that, and Naoki, AISHA, and Molly Daisy Scarpine are amazing vocalists
