I'll end up costing us. The current Steam and App Store have been a level playing field where indie developers can shove up a game with no hosting costs and people willing to try it because they trust these stores. As soon as you take away that trust and as soon as these stores have to start charging you for storage and distribution, then we get back to the pre AppStore days where it was prohibitively expensive to sell.
Yeah, because it’s so expensive to cover storage and distribution, that it justifies a 30% cut. Oh wait... epic store 12%, itch.io 10%, ...
Those companies charge 30% simply because they can, and no one really has a choice unless they want to completely ignore the mobile market. If game publishers would apply the same policies for taking over marketing, physical storage, lawyers etc. (the actually expensive stuff), they would end up taking a 95% cut... which they dont.
And no one forced apple to take a flat rate approach. They could just as well go for a revenue based approach like many companies do nowadays, giving small indies discounts. But yeah, I guess Netflix is more in need of that....
On top of that Apple doesn’t really give you much for that. With steam you get a full prerelease, communication and marketing platform with solid analytics. Google gives you some very solid analytic tools? What does Apple do, other then eating a piece of your pie for an occasional bump in the App Store?
