Guys, I have been playing your mod for a few games and I think it's great!
It adds the kind of decision complexity I always wanted in Civ games, in particular in government issues. I didn't like very much the mechanics of Civ5 original social policies, where benefits are cumulative and "stay there forever", like e.g. the skills of an RPG character ("+15 climbing", "+25 sword fighting", etc). Definitely, societies are not RPG characters, and abilities are lost when the society changes. With original Civ5 rules, your nation could be a "Monarchy-Aristocracy-Republic-Democracy", all together, which was weird. I like mutually exclusive choices and I like the government system of your mod, where, from time to time, you do have to switch your governments/policies even if you lose some bonuses.
By the way, since the happiness was removed from most 'good trading buildings' (compared to Procyclon's v9 version), managing the unhappiness is a real challengue in the mod, even in low difficulty levels! And I like it
Choosing wrong political choices (or delaying too much the technologies required for temples, colisseums, or theaters) implies being stuck with unhappiness for many years. After expanding your number of cities, new luxuries contained in the new land will not be there to save your happiness, as before! Nothing bad with that, I like domestic politics challenges!
Keep that good work, guys!
