Greenmangaming is my favorite. I don't recall the most recent time I purchased a game from Steam.
These aren't the same as Steam, but there are many comparable game stores.
GOG
Itch.io
Epic
Origin
Battlenet
DMM
...
There could be thousands of them.
The listed services operate their own platforms, many of which are publishers. The main origins are EA, Epic, Blizzard/Activision via Battle.net, and Microsoft through the Windows App Store and Xbox App. Sony also offers PS Now for PC. GOG.com provides DRM-free access with linking capabilities to at least Steam. Most online game stores distribute digital keys across platforms or offer installers that include keys. I've used https://www.gamersgate.com/ and HumbleBundle, either for platforms or physical purchases.
Not all games are accessible on Steam? I was looking for store names that offer exclusive titles.
