--- Comment #23 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

refining summary.

All the games in question here have one binary generated using Valve's CEG
(Custom Executable Generation) DRM scheme and that doesn't work properly with
Wine.

You can verify by (re)running game cache validation.
It will always flag these CEG binaries as inconsistent (size mismatch) and
tries to update it.
