The idea of a "YouTube fighting game" is funny to me - it's typically brought up by people who like kid-skewing YouTubers like Markiplier or MatPat who have larger-than-life stage personalities that probably translate well into movesets, but if you look at it from my YouTube viewing habits - which tends to skew towards analysis-comedy video essays, with bit of straightforward comedy/memes and serious breadtube stuff thrown in - it is completely incompatible. The idea of Kevin Perjurer having a Michael Eisner jumpscare super move or debating the legality of the Ashens couch stage is hilarious.
