All should pledge at least $25 if you don't have scholar badge already. You know you will buy it anyway when it comes out, and if you don't pledge then it might never get made
Even if you have scholar badge and don't want to give more, $1 will help with the game's ranking on Kickstarter which makes more people see it. Or you can pledge more and get a higher tier reward (you automatically have $65 reward - add the difference for a higher reward then select $1 reward)
