PC Gaming

Valve made it super convinient for their customers and they also took steps to encourage content creation with SFM, Source Engine, sharing their own assets. They created working cloud saving and mod sharing solutions, greenlighting a bunch of indies based on votes and being on the side of the customer in disputes over refunds with 2hr rule becomingthe new norm. For years, they provided and improved their service, so it's rare to see anyone complaining about that.

Ah, and Epic killed UT4 in beta when they found their initial zombie game mode that became Fortnite gave them that much cash they could start their own marketplace with regular giveaways and exclusives going on for years. I'm fucking pissed at them for that even now. It is irrational and personal, but Valve didn't kill my favorite game series, it's the opposite, since they kept slowly releasing and constantly updating Dota, CS, create Alyx, keep TF2 alive, and I'm only sad Alien Swarm would never see new content. In game studios and game marketplaces, Valve are golden.

But coming back to your initial displeasment with them, the funny thing is a lot of Steam games don't need Steam to launch. Unless devs implement some hooks and DRMs themselves, you can just launch their EXE file. Nobody really checks that, but that's the truth, and I've seen some lists of games that don't do that. On top of that, 99% offline games can be launched without internet with Steam only, you can even backup and then install some game on your PC offline if your client knows you own it. And don't forget family sharing - although they promised to rework it, I, my partner and our friends used it a lot, and although you can't use a game from a shared library when you are offline, if the owner plays it offline you can play it too at the same time without messing with each others' gameplay. This lazy implementation of DRM with many workarounds and general respect to even the sleakiest, cheating customer is why I still buy games there.
