Anyone who buys this game must be clear that it is extremely slowly updated. This version is extremely behind the Steam version. Urgent needed updates in an EA version.

Under this premise one can only advise against one purchase.

Yes, I regret having already bought games from these manufacturers.

Status:

The Devs says me gog is to blame, they have difficulties with the gog system.
GoG answer me that i have to update windows, my driver and use the repair option in galaxy and the whole support-bulls**** for the rejection of users, who ask gog to check with the developer why he does not fulfil his contract.
wtf gog? I cannot conjuring the missing builds from the devs with reinstall directx or repair the installation with galaxy. You have an contract and such things pull the look down from gog.

In fact, the updates for this game has a long delay. If I have good understand, they prefer update on GOG when a big update could be available. To confirmed by the Devs, of course.

Edit : Else, don't hesitate ask on the forum on Steam, if you want to clarified the situation.
