I think it's time for every big company to face it: Steam is PC's default store front/launcher.
No other company has even come close to Steam's software quality, features, pricing and trust.
Steam has been around for like, 20 years, it alleviated the platform's big piracy issue, it made it's way into markets outside of the big ones way sooner than the others, with prices that matched their economic conditions. I paid for games on steam in my local currency way before Sony ever set up their local PSN, back then I used to have to get PS gift cards from amazon us. Meanwhile I paid like 5 usd on call of Juarez bound in blood back then.
Even until very recently I couldn't even buy Minecraft Java edition with local currency, only way I got it was when MS decided to bundle Bedrock and Java together.
Point is, Steam has been around, for a long time, it has good features for users, it's overall a really stable software and as a storefront it brought accessible price to multiple countries, it also has almost 2 decades of user trust, and purchases on it.
Yeah, you have many options of launchers and storefronts on pc, but none even comes closes to steam. EA Play is mediocre, Epic Launcher is trash, it barely works and downloads on it never work properly, Xbox App is super trash, it always finds a random issue with it's app and you're forced to do a windows update, sometimes it doesn't even download properly, other times it just doesn't let you install on other drives, it's random ass encryption bullshit sometimes even duplicates installs and murders your disk space (PSO2), gog is fine though
So why should I bother with anyone that isn't steam at this point?
