The biggest thing that valve did that kept them in everyone's good graces is that steam's core functionality hasn't had any major changes in years. Dare I say, more than a decade.

It's a platform where you buy games, download them, and play them.

In the early days you still had to deal with all the bullshit, including third party launcher installs and crap to get things going, and over time, valve simplified all of that, making it easier than ever to take advantage of the core function of steam: buying, downloading, and playing games.

Literally the only improvement I can absolutely, positively credit them for, is making that entire process, easier, simpler, and quicker, than ever.

Sure, you can chat to people, track achievements, comment on your profile, comment on your friends profiles, buy and sell cosmetics on the market thing, even voice chat and I think they have a way you can stream your game to friends.... Not sure on that last one.

It's like Facebook, FB marketplace, FB messenger, discord, Twitter... And a bunch of other services, all huddled together to make a bastard child with the entire PC video game industry.... That's steam.

But the core mechanic that was always the main reason why steam was great, remains the same.

It's a lot of art, cats, and big tiddy cartoons. I haven't found anything too onerous in its UI, the community has a somewhat toxic level of positivity but that's certainly better than the general toxicity of most of the web these days.
