Temple Guardians returned to the "mysterious and deadly" bot defence of unfamiliar ruins.
Connies was laid on partly because I really liked the Terran Federation artwork and partly because of the concept of large populations sent out to colonise the stars and finally returning in despair, only to find the Earth no longer exists and they are GEN fodder.
Yamamoto is the final game I wrote, a tough slog against a fully-staffed warship of real size and presence. With that under their belt the team would have few problems dealing with the final few super-crawls through Luna.
So that's it, the whole "hard SF" mini-campaign, using downloaded "dungeons in space" and spaceship plans, plus some art from the TTF sourcebooks. I have no plans to revive it, but I hope this resource is useful for other GMs!
