Beware them spoiler comments like never before, partners.
It's not that I never thought this prior to watchin' the above video, but seein' it take form as an actual short film makes it even more apparent what impeccable potential RDR has to be a grandeur modern Western. 'Specially if John were t' be portrayed by a good actor lawl. I think it'd be incredibly manageable to adapt RDR's story into whatever sort'a media, particularly a movie or two (or three even, one per act with the final act also in the third film).
It's official, my status as fanboy is concrete since I've stated the target of my affections should become a movie.
