I've been trying to win with France on immortal at standard and epic speeds. However, I always seem to fall behind and am unable to fully utilize their UA. From previous recommendations, I open with tradition (unless incredibly close neighbors in which I go authority). I b line Stonehenge and take goddess of beauty for the pantheon. I settle 4 or 5 cities and go shrine-mono-council-granary-barracks/market. I also rush mathematics for compound bowmen and to build the hanging gardens. My capital somewhat resembles a normal traditional capital. I do try to make military units when I can with it but that isn't often. I usually get a religion, and take hero worship. I've experimented with other beliefs such as mosques, orders, 15% production, thrift, ceremonial burial and mandirs. I usually avoid very early wars, but will do a compound bowman rush later supported by catapults and swordsmen. By the mid game, I usually have to spend any faith I have on reconverting my cities (I normally enhance for zealotry and whatever catches my eye). I open and complete artistry. By this time I'm usually very far behind in tech and military power. I keep up fine in policies however. Any suggestions?
