I just put it on the Steam marketplace for $59.99. I didn't think anyone would actually buy it, but lo and behold some genius actually pays for it just two weeks or so after I put it on the market. Unfortunately, I can't spend it anywhere other than Steam, but I'm sure I can find a use for it nevertheless.
If I can get the same results with the new massive pile of trading card guff that I just bought (for around a grand total of $1.50, no less), I just may have discovered the most wonderful thing I could possibly envision.
