The Dark Ages and Beyond
In reply to GreenTongue (msg # 3):
I love falls.
One game I played with friends was in the final falling days of the Aztec Empire, had a whole collapse-of-society vibe as the Conquistadors and their allies took control and we fled with our families to what turned out to be an ancient alien starship.
The space adventures were fun, but that first campaign arc amid the collapse was the part that really stuck with me.
