"Following the successful launch on Steam, we are proud to announce that Lords of Xulima is less than one week away from releasing on GOG. On January 15th 2015, gamers will be able to play the DRM-free version of Lords of Xulima.
A DRM-free version of this nostalgic RPG title has been a common request by fellow gamers. We are excited to be able to launch Lords of Xulima as a DRM-free title, for Windows PC and Mac, for the first time ever.
Lords of Xulima is an original turn-based RPG with over 100 hours of gameplay, 9 classes to choose from, custom portraits, and a fantasy world that will provoke you to explore every dark corner.
If you have a GOG.com account, you can now add Lords of Xulima to your wishlist as you wait for the official launch. The regular and deluxe edition will both be available on GOG."
Hope to be able to exchange the steam backer key for a GOG one.
