Let me add one more TECH... to the mixture
ELECTIONS...
What if you had NO CONTROL over the vote of YOUR people??
This will move away from God-like game and further into simulation...
The question still remains... You start the game with either an Elderly stone circle...
or a Stone (Throne) in the middle of a Stone circle... that's determined by the bias of your Civ of choice...
On top of that you have the default Tribalism "government" type.
As turn passes and you unlock new techs and governments... you research elections...
Now by researching this tech you give your people the power to choose which Leader they do prefer...
So you might unlock Hatshepsut, Akhenaten, Tuthankamon, etc etc but it would be too powerful if
you could switch between them every time you choose... and it would be also bad if once discarded you had no
chance to get them elected again...
Playing with Egypt I guess Monarchy would be the most adapt government type and that would make the people
happier and more productive... elections could work anyway but it's just not the people voting... it's the High priests...
Or Play as Greece it's the Philosophers who votes... so you might get Alexander the Great if you are producing a lot of soldiers and your Commanders are getting victorious... the people would love this and vote for a Leader like Alexander... which you need to have unlocked obviously before this can happen... with one of the Greeks specializations techs...
Now FUN means there is a level of abstraction which actually makes Alexander IMMORTAL... if all goes well...
and the people is happy with it... you might get to keep it to the End of times... or untill you decide you had enough FUN and just quit the game (Finishing the game has never been WHY we play Civ...)
But with ELECTIONS your people could just get angry at him and vote him down... he could come back back later, or if the option where Leaders can die is allowed... they may never return...
The people might vote for Benjamin Franklin even... given the appropriate conditions... and no other Civ has taken him...
It's like a further RANDOMIZATION option that would keep the current hyper-shuffle style of gameplay
alive, but would add that tiny bit of historical context to the Leaders, that could bring up ...
EMERGENT GAMEPLAY.
We could also imagine people as units... workers... etc... they could form guilds... and by lobbying for one guild...
you could "steer" the elections in your favor...
Or just kill al the workers (armed civilians) of a town who expresses a Democratic consensus when your Civ actually needs a Julius Caesar successor that is the most Bloody and Autochratic possible... Nero???
So you start a psyop and burn down ... Rome... kill half the population ( and Senate voters) so you get your consensus... except thing get wild and Rome splits in East and West... and you lose half your territories...
NOW you get to choose which side to play... the "western" side or the "Eastern side"???
What happened when Genghis Khan died?
Did Mongolia, Turkmenistan, Kazakhstan, Uzbekistan, Siberia, all jumped out of nowhere???
If the game start to focus AGAIN on PEOPLE and WORKERS, it's much more likely that
Revolutions and new Civs could see the light of day in the future.
But here's the catch... there is a REASON why this Civ switch happens...
even if not historically true (which nobody is asking for) it will make players
understand the mechanics, and perhaps, fall in love again with the franchise.
