But whether a game developer sells a game in 1 store or 10 stores... the game developer must pay a fee to the platform owner. Every time.
Where's the outrage about that?
Some people think it's greedy that Apple charges a fee... but they're strangely silent when Sony, Microsoft, and Nintendo also charge a fee.
Thanks to the availability of alternative stores for marketing their products, game developers can have more flexibility in where and how they market their games including terms, potentially better commission rates, etc.
