Grab It Right Over
Another offering in the Winston Science Fiction collection with a cover by Alex Strumberg, this is a pretty strong offering in Winston collections. Even though its another juvenile science fiction offering there is plenty here that can be used with your old school science fiction retroclone games.
From the Inside flap of The Lost Planet:
The Lost Planet has a lot to offer the DM for his old school retro clone science fiction games. First we've got an entire planet with aliens, eco system, culture, politics and the rest of it to pull from. The lost planet of Poseida is fully fleshed out and ready to use. Given the background of games like Stars Without Number this is kinda of a 'shake and bake' world to insert into your favorite sector. We've had a ton of worlds in SWN that have been cut off from the rest of intergalactic space and the planet of Poseida fits the bill quite nicely.
