Aside from hosting cloud saves and Steam workshop data, there aren't many other services that justify a high fee to offset long-term costs. Steam trading cards, for instance, are just another source of revenue for Valve given that they also take a cut of sales from marketplace transactions.

Given that Valve's costs in developing Proton are offset by the higher Steam game purchase rates of Steam Deck users (myself included), the main benefit to developers is Steam's user base. As with Apple and the iOS app store, however, having what amounts to a monopoly in a market segment is not a justification for high platform access fees.

I mean… there’s Steam Workshop, Steam Voice, all the post, interactions, communities, etc.. all of this have to weight a lot on their budget.

My guess is that R&D as well as third-party Steam keys eat into their margins.

It could be more sustainable with this higher fee as well. Valve supports old games for a long time whereas console manufacturers pull the plug 10 years later. You could argue that Microsoft takes only 12%, but Microsoft has the luxury of being able to exit the PC games market at any time, or they can take a loss on it indefinitely. Valve needs to survive off its PC store because it's the only thing they really have
