How would everyone feel about a small prize like a F# mug or shirt via a digital zazzle gift card to purchase from the F# Foundation and a $100 cash prize? What amount of prize would make it exciting to participate but not so much as to make things cut throat? In the unlikely event that I win the person in 2nd place will receive the prize, because I created this because I wanted a game jam so I do want to participate, but I don't want to undermine my own event :P.
