When I think about Ringworld specifically and the Known Space universe more broadly, I'm always struck by what a rich roleplaying experience that offers. I've never been ambitious enough to undertake it, but if I were a third party developer, I might look there for a licensing opportunity. Hint, hint, nudge, nudge all you ambitious developer types... call me if you need a contributing writer.
As for you, Umbran - if you run it, keep us abreast of how it goes.
There are countless opportunities for hominid species and all that they entail. The Ring is covered with species the Pak collected (engineered?). There are the maps of Earth, Mars, Kzin and several Louis and the rest couldn't identify. Plus the city builders, whatever the root stock for the grass giants are -
yeah, I'd play this campaign, pretty much regardless of rules. Speaking of which, how would you undertake the rules? I might be tempted to use Savage Worlds (mostly because I understand it better than FATE). This part of the discussion might need to be moved to a new thread if it continues. If it does - someone let me know please.
