This was touched on a couple of times in this post but I didn't really see a clear answer, so I apologize for bringing this up again. The games listed here as DRM free, has anyone actually tested to see if these games can be backed up after being installed once from steam, and then moved to another PC to work?
I already keep a backup of all my Steam games downloaded and updated in case there's ever a legal work around (should Steam ever go under, as funny as that may seem to us now) to get these games to work without needing to be activated by Steam. So for me, unless they can be moved to another PC, this isn't particularly helpful in my case.
I have a fairly large Steam library (400+ games I think), so I'll try to make some time to test some of the games I own that haven't already been tested.
I think that's how people have been testing them. I know that with the games that I have that are DRM-free, you can just copy/paste the installed folders to a flash drive or something and even play them straight from there on a different machine.
