We've already got the Magic Faction set up, and the Tech Faction is too for the most part. But here is where I have my ideas to add. We are told that the nobility took sides in this conflict: Some with the Mages, others with the Scientists. We've got the ones that sided with Scientists, but not the ones that sided with the Mages or the Scientists themselves. The way I see it, the conflict would be a lot like the Cold War: The Mages and Scientists would use the societies of the Glest setting as proxies for their greater conflict. We've got a faction to represent those that ally themselves with the scientist, now we need one more of those plus two to side with the mages. Another idea is to implement a civics system like that used in Civ 4. For those of you who don't know much about that, the civics system can be defined as this:
A set of options as to what government, economic system, and cultural orientatin among other things your civ would have, as represented by unique penalties and bonuses.
For instance, what is now defined as the Tech Faction can choose to be led by a Feudal Nobility and have a bonus to the unit's coming from the barracks, or have a Technocracy, led by the scientists themselves, giving a bonus to units coming from the technodrome, as well as quicker research time. There is are also diplomatic bonuses and penalties. Technocracy will lead to more conflict with the mages than Feudal Nobility, who can choose either side) and many heroes have their preference; Meaning Technologue Eirn would be likely to desert if you changed to a Mage Order Civic.
Picking one civic does not give you the bonus automatically, as there is a waitig time required before the old civic can be overthrown. That is what I have so far. What do you think?
