The online mode is stripped out of the GOG version. There should have been a mention of that on the store page. You can find videos of the main menu for the Steam version, and on it, they have an extra option called "WB Play" and it also has cycling banners when it's connected to online. This version does not have the banners nor does it have WB Play. I can only assume WB used Steam for matchmaking and was too cheap to bother with servers for other platforms. I wouldn't have bought it if I had known this beforehand. Really dissapointed.
