The misconception of pc gaming wiki mistaking pc store as drm.

[silverkeeper 3]

I started checking the actual DRM from my Steam catalogue to contribute here. I'm not proud of my constant rectifications, but now that I've found this thread I can ask: does a external seller (i.e. Humble) technically sell games with Steam DRM if the game itself is DRM-Free on Steam?
I started using the "Keys" column to indicate they sell Steam keys, but realized it's meant for stores that sell DRM-Free versions and give you keys for other stores.

Guess in this case you can put the game sold by Humble as DRM-Free and indicate that it sells you a Steam key in the notes?

Steam icon in the DRM column for non-Steam stores only indicates that that store provides Steam version of the game. It doesn't indicate if the game is DRM-free or not, that's the job of the Steam row itself.

Sometimes stores provide a standalone version and Steam key at the same time. In such case DRM column should indicate the state of standalone version(often DRM-free) and Keys column should have Steam icon. And again Steam icon in the Keys column doesn't indicate DRM level of game but just provision of key.

And the same applies for other stores.

But I'm not sure if this info is mentioned in the guide.
