OMFG, I can't believe that people actually PAY for fonts!?!
I found out that the smaller text on the FU cards (not the titles) is a font called "Garamond Light Condensed" and also on Munchkin Bites (I didn't mention it before because I don't own it) the title's font is "Gehenna" and that the both of them are like $12-$20 a piece!
I'm amazed that you can make money on fonts.
I guess the search is on for "free" versions of these fonts...

P.S. I'm still looking for the names of original Munchkin's smaller text, Munchkin Fu's Title text and both for Star Munchkin. Bites, I'm not too concerned about as, like I said, I don't have it yet.
