Steam doesn't enforce DRM. You can usually go to the game files and just click the launcher from the file manager and the game will run without steam getting involved. Sure its not the most officially supported, but they hardly prevent you from doing it.

I think this is incorrect. I believe most Steam releases do require the Steam runtime to be present. Trying to open the game directly will "work", but that's because it's invoking the Steam runtime - just without showing the launcher.

Examples:

* Dead Cells has Steam DRM: https://www.pcgamingwiki.com/wiki/Dead_Cells

* Hollow Knight does not (will run without Steam if you copy just the game files): https://www.pcgamingwiki.com/wiki/Hollow_Knight

I don't think it's even a requirement. Games can utilize steam apis to have a better integration with friend list / invites / drm purchasing...etc. But they are not required to. You can just upload a standalone executable without calling steam api at all, steam won't prevent you from doing so. Actually, most visual novel games is in this category. Copy the game file and run it at some other place will just work.

Another example is original sound tracks sell as game dlcs. They are simply downloaded into game directory, nothing is protected.

Steam dont require games to have any DRM. Developer might avoid Steamworks altogether and can also make it degrade gracefully: for instance disable online features if Steam API is not available.

This is entirely up to developer to decide how they use Steam.

PS: I am game developer.

Right, but OP said Steam "doesn't enforce DRM". Saying they don't require developers to implement it is different than saying they don't enforce it.

[stavros]

Different how? If it's not required, then it's not enforced, no?

[xiaq]

I guess "Steam doesn't enforce DRM" can be understood to mean that Steam doesn't enforce DRM regardless of whether the game uses its API.

[stavros]

Oh hmm. I don't know exactly how it works, but I think Steam DRM is different from using the API for friends and things like that.

Very not sure about that, though.

Game developers are not required to implement Steam DRM to sell their games on the Steam store.

If a game developer chooses to implement Steam DRM, Valve will enforce it.

[stavros]

Yes. What is the other meaning? DRM that doesn't enforce protection?

can confirm, I was trying to set up my(is it really mine?) copy of obra dinn for my mother to play. and was unable to get it to run given the time I was willing to invest in it.

I was vaguely surprised because I figured that obra dinn being a small single player indie title would not have any drm. and I don't think it does. I think just linking it to the steam dll(for steam integration) makes the check occur. I suspect the solution is a bogus steam dll. but did not find one in the couple of minutes I was looking.

Note that you can copy a game to a friends computer then authorize them to play it, so good for valve, but I did not want to set my mother up with a steam account. so did not use this feature.

Valve provides a way to use Steam as DRM but it's entirely optimonal. There are many games on steam where you can just run them directly or copy them on to another computer and they run fine. So its just up to the game publisher to decide what DRM they want.
