There is no way companies are passing that 20-30% to the consumers.
"Epic’s CEO Tim Sweeney has effectively thrown down the gauntlet to Valve, saying that if Steam matched the Epic Games Store in terms of dropping the cut it takes from developers to 12%, Epic would stop pursuing the policy of securing big-name exclusives."
The entire point of the EGS is to get the industry to lower their skimming. And you don't even have to invoke altruism: if Epic continues to take 12% of every transaction and grows the market ten-fold, that's still more than a 30% cut of the market today.
It is a sad testament to our time that it is inconceivable that a person just wants to better the situation for all involved.
I'm a game developer and the EGS is the best thing that's happened to us as developers AND to us as gamers. And our games aren't even on the EGS.
I'm sure if there was true competition in the app store market, other app stores could be more efficient with the 30% cut that the App Store takes, and pass the savings off in order to compete with rival app stores that take 30%.
