Hey so I just bought civ 5 + G & K in the steam sale. I am looking for some advice on how to effectively play as Napoleon (France)
1. What techs should i "beeline" if any?
2. What should my priorities be?
3. Is my unique advantage (extra culture per city) any good? I think it adds up if I go rapid expansion.
4. What social policies should I go for?
5. Should I be aggressive/passive in nature? Or can I do both just as effectively.
I have looked around the forums and see France does not get much love. Is this because France is not worth playing? Maybe that is the case, but I have had fun so far learning the game as them.
France has always been a favourite of mine. They are good for beginners as the culture bonus really helps things get going in the start.
They can be played for cultural victories, but are also military strong.
Now you can play them many ways, but I always followed a scheme, where I kept my cities low (3 or 4), while getting gunpowder. This helped me fill out social policies, I always followed the combo of full tradition then full honor, it's just fun

. Opening with trad, but getting a single honor point to hunt barbs down. The raging barb setting can enhance this strategy. City sprawling will actually quelch the France culture bonus, the policies just get too expensive. But it's a strong bonus with few early cities.
I would basically research a few early military techs, but generally aim for education. As soon as I could build universities I'd go into the tech tree and set it straight for gunpowder.
This way, I would defend with a couple of horsemen, later turn knights. You'll need those. A sword man or whatever my starting warrior turned into (he is the medic, with cover and rough promotion

), some archers, and very often I'd also have a catapult or 2 if I had been attacked.
I'd basically just hang back, while getting heroic epic and armory in my production city. When gunpowder showed up, I'd build and buy the backbone of my army, 4-5 musketeers and I would be on my way to take a capital or 2.
This was before G&K, where you couldn't upgrade swordmen directly to gunpowder. But by doing this still, you'll get the benefit of heroic epic strengthened musketeers so it hasn't exactly worsened, as strategy.
From there the game would be open for all victories, on Emperor and often Immortal too. You can get another military edge with Foreign Legion, but from there science and even culture (if you have puppeted mostly) are also possibilities.
