But the situations I described are already possible in FfH2. You do get Hyborem Republic+Liberty all the time. I think I even built the Mercurial Gate as Hyborem once.
Right now, there is really very limited tying of the story to the game mechanics. And I think very stringent rules is actually a bad way to do it. Instead, you should shape the civilization's traits, bonuses, and penalties so that players want to play the civilization in a story-appropriate way. Telling the player he just can't do something seems inferior to encouraging the player to do the appropriate thing.
For example, I think Khazad is done really well. You have a strong incentive to stockpile large amounts of gold in a few powerful Dwarf Fortresses (heh, my other favorite game), which means Runes of Kilmorph is very valuable as a religion for you.
I think we agree on most of the points actually. I guess the way I'm thinking about it is that even if Hyborem has Republic and Liberty, it is still Hyborem and the player plays the Civ as though it is Hyborem. That is the advantage of NOT having the civics define the main characteristics of the Civilization; since the civics are important, but not so important to be defining,the flavor of the Civ being played is not harmed by the choice of civics.
If, however, the main power of a Civ and how they develop were a product of the Civics, because the civics are so defining of strategy, then I fear that these powerful civic chocies will define the strategy and play of the civ, and indeed Hyborem may not be Hyborem any more.
I want to civics to be in the middle, like choice of tech path, type of military built (magic vs footmen vs cavalry etc.) -- important enough to matter and help optimize, not so improtant that it defines the strategy.
Perhaps the ideal situation would be civics specific to each civilization. Assuming this solution is infeasible (with a few exceptions like Crusade for the Bannor), I would err to keep the power of the civics in check.
I absolutely agree that having Hyborem run Liberty and Republic is 'bad', but I can deal with it as long as I'm still feeling like it is Hyborem.
Perhaps another solution tht wouldn't be too hard to implement is to not allwo certain Civ's or alignments to use some of the civics to eliminate the more egregious cases.
Best wishes,
