What is the point of starting a new topic to address a year old topic that is now moot? Are you expecting more retail releases of D:OS?
It has yet to be decided if there will even be a PC retail release for the EE.

Some of these 'facts' are not actually facts in this case. D:OS does not use any DRM or require Steam to run (just to install, update or use Steamworks functions).

If people don't want to use Steam at all, they can get the GOG reelase of the game.
