One of the coolest features that PSO had, back in the day, was that you could craft and customize a series of "Symbol Chat" cards that you could display on demand. The cards were largely designed so as to need minimal text and/or language, making it easy to display emotions or needs quite quickly without the use of a keyboard. It was largely "generic emoji" style, in principle.

I loved it because I found a way to make it fox-themed, and then found a way to make it silly.

What's this?
