Earlier quoted context omitted.
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.pcgamin…
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.
