The hittites are a famous civilization who lived around the same time of the Egyptians and helped spread technology due to their many wars to various parts of the world.
The canadians have not conquered any lands, made any great cultural or scientific achievements as a nation (I know there are tons of brilliant canadian scientists and whatnot). Those are the primary criteria for qualifying in civ as being a "civilization"
I have come up with yet another way to modify how your gov is (in addition/alteration to my previous posts on government)
Everyone should start off as "tribalist" Depending on how many units they have, the measure of economic control they have, and what kind of "public improvements" (see previous post) they invest in, and if they hold elections or not, size of empire/cities within empire, a civ will ultimately branch off of "tribalism" into various stages of government without a revolution. A revolution will only occur if you must switch trees. For example, a tree could look like this:
N.B. I set the tree up like this:
(Government) -- (Criteria for government change) --> (If criteria are met, government changes to _______) and so on and so forth
Tribalism -- elections; small, contained empire of medium-sized cities; public parks and no military --> City-state Democracy -- Elections; Vast empire of large cities; medium military with conquests; laissez faire (no support for trade unions, conservative economy) --> Imperialistic Republic
Here's another possible tree:
Tribalism -- Some elections; public works, more controlled economy, somewhat small empire --> Monarchistic Commune -- Some elections, controlled economy, public works, lots of healthcare, lots of education, lots of union support --> Socialist Republic
I included only three "stages" for the sake of simplicity's sake in making the tree. In the real game, one could have many stages. Essentially though, to qualify as a change in government, one must maintain certain criteria for a certain number of turns and then there will be a little pop-up saying "Our people all agree, we have become a Dictatorship!" or something to that extent.
Elections: Basically, this could be called voting, referendums, etc. If you are about to go to war, make a drastic change in any of the sliders, or sign a trade embargo what have you, a pop-up will appear asking if you would like to have a vote for this. You can choose yes or no. Then, depending on what factions are dominant at the time (could be random, could be depending on neighboring/frequently trading countries) a vote is held to see if the people approve of your plan. If they approve, then you can proceed and the people will be get slightly happier. If they disapprove only a little bit, then you can continue but they will be disgruntled, if there is overwhelming opposition and you continue to do the action anyway, the computer will play for 5 turns and try to restore things the way they were previously.
Every now and then, a random election will be held. In this election, the people take a vote to see if they are pleased with what you have done since the previous election. Ways to hurt your standing include if you have drastically damaged the economy, drastically hurt international approval rating, used forced labor (we should have the option to do either one, no matter the gov.) etc.
