Done.
> We also seem to have a plain [`playstation`](/tags/playstation). I'm not 100% sure if it's a catch-all tag for all Playstations, but if it is, then [`playstation 1`](/tags/playstation+1), [`playstation 2`](/tags/playstation+2), [`playstation 3`](/tags/playstation+3), [`playstation 4`](/tags/playstation+4) and [`playstation 5`](/tags/playstation+5) (and maybe even [`playstation vita`](/tags/playstation+vita) and [`playstation portable`](/tags/playstation+portable)) should imply it.

"Playstation" seems to be the name of tyhe general branding as well, so done.
