I want to start making games. Need clarification first.

With Kickstarter remember that any money from backers that goes towards pre-purchasing the game still counts as earnings. They are technically buying your game, after all. Any money paid that is “attributable” to the cost of the game will have royalties due.

The example I saw goes like : if one tier includes just the game for $30 then you owe $1.50 in royalties. If a higher tier for $50 includes the game, a t-shirt, and a poster then $30 of the $50 is attributable to the game (while $20 is attributable to the poster and t-shirt) so you will owe $1.50 in royalties for that backer as well.

Or something like that. Obviously, if you’re running a Kickstarter, you’d probably want to run your numbers by Epic to get clarification from their lawyers/accountants.
