I just watched that video of Sonic...I think there are probably some songs (for some games, maybe not iconic games like Sonic) I would have preferred slow-PAL, whilst others are best left at original tempo.
It would be fun to see if a some songs actually improve.
Of course, I can only say this from the vantage point (privilege) of having experienced games at 60gigawatts...it's a novelty for me...I would be more bitter if slow-PAL was all I had.
I would have just stayed in the arcades until all that shit blew over...PS1 era, or whenever that was. Gameboy will do.
You are crazy.
Home consoles = absolutely essential.
I would have absolutely indulged in slow-PAL.
