From the first post... "Dragon Age: Origins (Europe)"
Does this version not have the inert EA Core files or disk check? If so, where do you get the European version? Thanks!
It does have a disc check, but for the purposes of this list that isn't counted as DRM. At the end of the day you can still install and play the game without ever connecting to a server.
The DLC, well, that's another thing altogether.
Age of Wonders, Populous II and X-Com are playable without the CD so I guess they are pretty DRM-free.
Not sure if you can backup the CD-files on run the installer from other sources without a fuss though.
PREY (Europe / UK Version) removes Copy protection with 1.4 retail patch the 1.4 patch makes the game a NOCD / NODVD VERSION.
Funny this game is still being sold on E-bay!
Thanks. These are a tad older though, so I'll leave 'em out, because including every pre-2008 game will result in a very, very long list.
