I am not font-nerd, but i have to admit that a good font is something memorable. Like the one from GTA, quake,etc...
A good font can do much good, and a bad font could do much evil, this is like everything else. having a neutral generic font is bad but at least is readable, could be a lesser evil. Maybe use a bitmap font with the font external, so some people can create "user made fonts", like.. he.. the C64 font based on the original c64 font
