This. As game developer this is a huge problem since outside of top 1% industry is shit poor and platforms squeeze it badly.

Unfortunely needs of game developers and customers are not exactly align. Valve is good steward of their outsized market share when it's comes to gamers interests.

Epic Games tried to shake market with "gamers dont matter" policy (no reviews, no community, worse services) and low fees and failed miserably.

As game developer I'd love to see platform fee of 10%, but as gamer I dont want to buy my games and give power to Tencent, Microsoft or Google.

I could only dream that customer-first platform not owned by VC / PE money like GOG could compete with Steam. Unfortunately unlikely to happen.
