I am so so so so excited for this...
I have felt for a while that the Explore part of the 4X in Sins was a bit lacking, and this DLC not only addresses but completely overhauls that system... Thank you, Yarlen and Stardock and Ironclad too if they are not too busy creating their new game.
I will most certainly purchase this.
To many more Sins Rebellion DLC packs!
And to HouseRalan,
How can you be unhappy? Sins Rebellion is getting more content! If it is similar to or inspired by a mod, who cares? And I'm sure that the designers did not simply copy and paste the ideas and planets from mods into the game - they are enhancing and putting their own spin on it. And evidently they are tying it into Sins lore. All of this sounds great to me.
