A quick and simple change to the font should be all that is required.
It would look better and take up less characters when writing things out. Instead of typing "Only 25000 credits", a player could type "Only $25000" and the game would simply have the Galactic Credit symbol in place of the dollar sign or whatever the player has locally.
Immersion and laziness in equal parts.
I know this is not a big thing, but I've had this idea bouncing around in my head for a while. Would it a bad or difficult idea to replace the common currency characters(dollars, pounds, euros, et cetera) in the in game's font with the Star Wars Credit currency symbol?
