I’d guess close to zero. A few years after graduation, I bought the card game he created not knowing it was his work until I was back at my hotel room and looking through the manual and recognized the logo on the back page of the manual as the same logo he used on the Escape from Harvey Mudd.

(Fun trivia, neither Matt nor I actually graduated from Mudd. He ended up getting his degree from Pomona College and I got mine from Pitzer.)
