Woo, we're all updated again! I hope everyone's holidays are going well/have gone well!
I was really surprised about The Bureau: XCOM Declassified being DRM-free now; that one launched with Valve CEG (and scanning the files reveals that it's still there, but maybe it's just inert now), so the fact that it runs without an internet connection at all is shocking, let alone without Steam.
Strafe seems to be DRM-free, tested on Windows 10.
Also Merry Christmas all, hope everyone's having a holiday season.
Are you talking about the Millenium Edition?
