Chthonian Stars is/was an interesting product with some nice contributions to Traveller.
Frankly though, I have given up on the company entirely. I'm not particularly interested in The Void at all. They produced some exciting and fresh ideas for Traveller and I'm more interested in Traveller than a new and unproven game system.
For whatever the reason, they've fallen out in some fashion or other with two publishers, plus they appear to have no real grasp of staying in contact with their customers.
Given all of the time that has elapsed, it surely wouldn't have been THAT hard to make the PDF available as a POD format. Maybe given the problems they are now hacked off with trying to bring their games to the market, but I'm not feeling much interest in communicating OR in providing product.
Personally I see them as close to flatlining.
It's a shame because I would have loved to have seen this as a whole Traveller product line.
