Princess Ryan's Space Marines

[Conquistador]

I keep bumping up against references about these rules from "way too far back to be remembered by any one under 50" comments.

I have never seen the rules in person, much less played them, but can someone describe them compared in terms that old school "I cut my forceblade HTH combat training on Ralnai" types like myself would understand (FanTac/FGU Space Marines/Starguard for example)  - I have played Traveler (1980s,) Stargrunt II and Dirtside II (1990s) over the years so comparing them to those also works.  I would like to know why people seem to love them/hate them so long after their heyday.

Gracias,

Glenn
