And now I know why the option in the menu in Final Fantasy 7 for "calling" other player characters (to rearrange them / form a new party) is titled "PHS". Mystery solved, 23 years later.
I miss that SquareSoft era. The standalone Final Fantasy games were great. Still are should one forget a bit too much. Words and their context were often rich and intriguing.
Entry to an official building in FF12 featured a docent, not a receptionist or greeter or guard. Just one of many examples where Square found something a little obscure to spice the overall experience.
