Hello,
I was reading your discussion about the Bene Gesserit, Corrino & Freeman factions. I actually don't think they should be factions but replace the BE affinities as they represent the 3 main political motivators on Arrakis at the time:
- Bene Gesserit: their ongoing quest for the Kwisatz Hadderach
- Corrino: "The Spice must flow", the status quo must remain between House Corrino, the Landsraad, CHOAM & the Spacing Guild
- Freeman: Shai Hulud and the dream of a green Arrakis
Advancing in affinities through quests & techs can be used to include the original story line, or other possibilities off course. In my view the Freemen could replace the BE Aliens, and be recruited by factions having sufficient Freemen affinity.
They could all three offer interesting advantages & possible wonders and will set houses against each other as in BE and the novels. The Golden Path would actually be a combination of all 3 affinities.
One last remark: on the strategic resources: there should only be Spice, it's kind off the whole point ;-)
Please let me know what you think!
