Playing as France in my online matches has served me well, and I understand why some folks host "No France" as a game rule.
A while ago, someone in the multiplayer forum posted a great policy strategy for opening the game..
1) On Turn 5, Tradition >> +3
in capitol >> 6
/turn
2) On Turn 10, Liberty >> +1
in each city>> 7
/turn
3) On Turn 19, Collective Rule >> +1 free settler = +4
in second city >> 11
/turn
So in just over 20 turns (allowing a few turns for city placement), France has two cities already founded, and they're two relatively quick policies away from getting an important early-game wonder via Great Engineer. At times, this start has provided enough of a good boost to provide a small advantage for at least the early-to-middle phases of the game.
Meanwhile, on Turn 20, a competing civilization would often be just starting into their second social policy, hoping for a cultural goody hut hit. The March patch changes to Tradition and Liberty have almost made France a bit over-powered, in this respect.
