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.
