Was curious if anyone knows what exactly has been updated for the GOG release as I've only played these on Steam. I know about NewDark being included but I also read somewhere that Thief Gold uses the models from Thief 2. I would prefer the original models if possible. Would I have to patch the game if this is the case?

the GOG build includes no additional or enhanced resources. bugfixes only.

Sweet. Thx for clearing this up!
