BlackThorny: I didn't see it on the list (and didn't find results using search), but
super panda adventures can run just fine without steam.
I didn't try to move the game folder, but I did try to run it when the steam client isn't on, and it worked just fine - even though it couldn't run at all through steam offline mode as it was downloaded via Family Sharing... which makes me a pirate? o.O
edit: Also
Adventures of Shuggy which
is on the list
didn't work when I gave it the same treatment...
edit 2: Why are there games like 1000 Amps, Aztaka, Blocks That Matter, Bob Came in Pieces, Containment: The Zombie Puzzler, Cortex Command, Crayon Physics Deluxe, DEFCON,
Faerie Solitaire listed with No information whatsoever? I'm actually interested in the latter one.
edit 3: Also I don't get why free games available DRM-Free elsewhere like Heroine's Quest: The Herald of Ragnarok are included in the list?
If you want them DRM-Free just don't get them on Steam in the first place!
If you do want them on Steam then losing the achievements is ruining the whole point of having them on Steam o.O
You can't play games from Steam Family Sharing (now: SFS) in offline mode, that would defeat the whole purpose of SFS. It would also be technically difficult if it would be allowed to play SFS games offline. But it's only the Steam client that restricts the access, so playing DRM-free games without the client is still possible.
As for
Adventures of Shuggy, I thought it would run on a different PC. Maybe you had to install the latest DirectX from the game folder, I'm not really sure at the moment. If you installed
Adventures of Shuggy through SFS, then it could be that it won't work for you. Some games are DRM-free but need the launcher when installed through SFS, at least that was the case for
VVVVVV on Windows for me.
The games without information on the list were mentioned somewhere to be DRM-free, but nobody specified on which OS they are DRM-free as there are differences. I would simply assume that they will work under Windows as most people who don't specify their OS won't use Mac or Linux, but without sources I won't add them as DRM-free under Windows.
This list simply lists games on Steam without DRM. Why does it matter if it is available DRM-free outside of Steam or not? I think that Steam is convenient with its updates and Sales but I don't like the DRM-aspect, so I launch Steam once in a while to conveniently update and download games and then play the DRM-free ones without the client. That will probably change when GOG finally launches the Galaxy client, but let's see if it will be any good or as crappy as the Desura client.
