"the ∆ refers to viewpoint; it represents one's head or direction. ☐ refers to a piece of paper; it represents menus or documents. the 〇 & X represent 'yes' or 'no' decision-making." -teiyu goto on what the playstation controller symbols mean.
@moshboy @neauoire curiously this mapping never took into account the ol’ platformer method of resting one’s thumb over both square (run) and x (jump) simultaneously, which was pretty ubiquitous in the NES and SNES era. Though granted this wasn’t used as much when gaming moved over to 3D!

@Jickelsen @moshboy @neauoire I have prior art that says he's full of it. Just four convenient symbols...

This book is from 1983 - check out the four buttons on the side of the watch of the future! 😊

Damnit. Edit toot isn't working, forgot to add alt text.
@Jickelsen @moshboy @neauoire however, it matches the semantics of the SNES controller which has A on the right ("OK") and B to the bottom ("cancel"). I remember Frank Cifaldi talking about letting players of Digital Eclipse NES ports swap bottom-and-right mapping with left-and-bottom, because "we're not savages" or something like that. I think the Switch Online NES app also allows that?
@moshboy and then someone decided to swap X and O in the west, ruined it all, and brought us the world where Microsoft and Nintendo have the same letters in reversed positions
@moshboy I always thought it was numbers, based on the number of sides each shape has
@moshboy whether or not your source is accurate, aren't they referred to as "sacred symbols"?
@moshboy I always thought it was circle for pizza, triangle pizza slice, square is pizza box and X is no pizza 😄
