Crowdfunding fee

Well that’s the thing, for the game I am working on, they started the Kickstarter over a year ago, and weren’t even using UE4. Now that they have switched to UE4, the game’s potential has gone up quite a bit. For their tier $30, it was access to open beta, for $40, access to the game itself. I find it hard to believe that the game will be sold for only $10, as I’m sure it can sell for $30+.
