UI : System Font

It would be nice to have a drop down that lets the player pick either a point size for a "normal" text in the game (and everything else is relatively sized), or an amount to add to/subtract from all of the existing font sizes used in the game. Setting a custom font is nice, but nearly all of them show up way too small.

They do show up too small. Being a font enthusiast, I would very much like to use some "fantasy" fonts available to me, but the text shows up too small to be legible. I understand that these fonts will unlikely have support for Japanese characters, but it's the price I'm willing to pay!
