I really wouldnt buy this on GOG currently. It seems like we are a few updates behind, we have to login to get those updates and register with a valid key on their website. BTW my game still didnt update to the latest version when this was done. I really wanted to play this game and support the developers. Now i really wished i waited for a sale or didnt buy this game at all. Really upsetting the road blocks they put in the way on the game even when its meant to be DRM-Free. At the moment i would not recommend buying this game until they remove that feature and give us the current update/release.
