Just finishing up the code and testing and I should have it out in a couple of days along with the Mud world and a bunch of bug fixes.
Next month we're hoping to do three, as long as we can find the time between having summer fun.
So far two rare worlds are planned and along with a surprise I'll post later;
1. Storm/Hurricane World; a cold wet world covered in near-constant storms.
2. Rogue planet - A Cold Dry world that has been thrown from its parent star, found in the weird and strange places of the galaxy.
As always feel free to pitch other ideas you might have!
