You enjoy your sci-fi, but you also have a hankering for horror. Maybe your Delta Green campaign just didn't have heavy enough weapons for your taste. Well, someone put your Cthulhu in my Traveller, and the combo is awesome!
I really enjoying working my way thru the Chthonian Stars Core Setting for Traveller. It's not a mash-up I would have thought up on my own, but its a very good match. The books is full of short fiction, which normally I can't stand, but in this case it is very evocative of the setting and a good tool to engage the reader.
It scales down the default Traveller setting to just our (now fully colonized) solar system, and I think the change in scale works very well in making the horror more immediate.
Character generation is changed a bit from regular (Mongoose) Traveller, as many careers have been adjusted to the new setting. New space ships, which makes sense, as they are made for traversing the solar system.
We are given three short adventures, which is nice, but I would have appreciated a page or two of adventure seeds. Maybe I missed them, as flipping thru a PDF does have disadvantages over print.
Overall, I'm very excited by the Chthonian Stars Core Setting. I might find a use for my Traveller core rulebook now. If nothing else, the setting book deserves a second read thru.
