I can't imagine any competitor is anywhere near what Steam has in user numbers, however many publishers have their own exclusive clients now. EA with Origin, which actually has great customer service (you can chat with customer service reps without waiting a month), Activision-Blizzard though I think Activision still releases games on Steam, GOG which I have no experience with but hear its good and then there's Uplay which is fine, integrates with Steam. But I like many Steam users am invested in the platform, I just wish they did some things better.

You heard right. They have quite a good setup: the Steam-style GOG Galaxy client is entirely optional, you can also download, install and run your games manually without hindrance.

Well done web site with lots of user reviews. They also have very cheap older games and regular freebies - they're such a nice seller that you feel like buying something more expensive (Witcher 3 at half-price was a good deal ;-)

Edit: they also have a 'connect your Steam account' feature that allows you to have some of your Steam library games added to you GOG library.

When I tried last fall, I was able to buy Total Annihilation on GoG on Windows 10 client, but unable to launch the game on Windows 10. That was rather disappointing - no messaging it would be broken before purchase, no insight into if it would ever get fixed.

In instances like those, they'll refund you. I haven't had to do it myself, but I understand that to be the case. Since they sell a lot of old games, some of which they have to actually use cracks to disable the DRM on, they don't always work on newer machines unfortunately.

Activision has historically released their games on Steam, but their last PC release, Destiny 2, and their upcoming game Black Ops 4, are both only on Battle.net (Blizzard's client). Looks like they'll be releasing their games on Battle.net from now on.
