Steam games that are DRM Free

A curator group that lists Steam games that can be run without the Steam client (DRM Free). Won't list games that have DRM free versions on other services/sites, just Steam games.

I used wikia[steam.wikia.com] for initially starting the group with info. If its inaccurate I apologize, let me know if a game have been labeled incorrectly. Also, this list is about the Windows versions of games.
