It’s false equivalence to claim steam has a monopoly when you’re literally giving epic a monopoly on your games for financial kickbacks between yourselves that in the best case doesn’t impact the user and worst case actively compells them to a much worse platform. What epic and gearbox did is monopolistic, what steam did is just make a good enough product that no one gives a sh*t about EGS. If you want an actual competitive store front, make something your users want, not your business partners. Gog is struggling but it’s still my first goto for games because even if it’s missing all of steams functionality, it gives me ownership of games that can’t just be revoked or broken by publishers. That’s a value add I’m willing to pay for. Paying more so publishers can make more money and sell a worse experience through EGS ain’t moving me.
Name any Steam exclusives. I can think of Half Life Alyx; you could get everything up to The Orange Box and even Portal 2 on disc.
It’s a little different to have your own games exclusively on your platform than to pay other devs not to release on other platforms, and it’s entirely different if devs just choose not to release elsewhere because no other store is worth the effort for them.
Steam did exactly that for years under the “Steam Greenlight” prism where users voted for games to be released on steam with the condition that they would be exclusive. They only stopped it when they decided to go the Amazon route and sell any old shit with zero curation instead.
And Tim Sweeny made the offer to stop offering Epic exclusivity and even sell their games on Steam if Valve offered to provide their service to developers at the same rate as Epic.
But Steam charges nearly triple what Epic does and can depend on gamers to defend them for some reason.
