This is another thing bothering me for some of these suggestions. I don't think some people know how much it costs to have a game submitted to consoles. Tip: To buy a fucking console dev kit, submit your game for review, and then put it up on the store is WAY less than $5000 altogether. Why the fuck should an open platform like PC with a store like Steam that literally has ten of thousands of games be so expensive compared to every other platform to submit your games to it for?
Devkits are the most expensive part of console development, to get a devkit you do need to be approved and all that first, and on PS4 & Xbox One a Dev Kit costs usually somewhere between $2000-3000, but both often they will wave the upfront fee aside to be paid off by sales afterward. but both of those gives you the various tools you need, developer consoles, programs, etc., to be able to work on and test your game. It's a full-on devkit that costs $2000-3000, not individual game processing.
A PC and a game engine is all you need to make a game for a PC, there is no devkit required for Steam itself. I also think Steam going closed off like consoles is a terrible idea. A big part of the appeal for PC games is the fact that it's an open-ended platform. Hell, Valve says as much in their post on Steam Direct. They don't want to shut out games from coming.
I just feel there should be some other metric being used here other than money to submit a game to Steam.
