most are quite happy with the services they get back from that 30% cut.
I agree with most of that, but this part just isn’t true. 30% is highway robbery. It’s a scam. But PC gamers are trained that Steam is where the games are, with few exceptions. If you don’t pay steam their cut, your game doesn’t sell at all.
Consider all that goes into development of a game and compare that to the effort/infrastructure to host a download and display a webpage. Is Steam really providing 30% of the game experience?
I think Steam could be profitable at less than a 10% cut.
You also recognize that 30% of each game sale applies to each game sale, right?
Do you really think 30% of developing a game is hosting not just the original game, but also the updates and the save files? CDNs only make it cheaper.
Steam is able to charge 30% because they effectively have a walled garden on PC games. Very few publishers are well known enough to successfully sell their game outside of Steam.
It’s not as egregious as the Apple or Google stores, but they’re basically all in this together. It’s like the old mob families where they split territory.
