Here you can see my completely botched try at a france opening (first time i really tried it). Its not even 8 years in the game and I allready have over 50k troops, with some Vassals (completely screwed up the vassalization of Savoy though).
DO note that a lot of stuff could have gone better here, also I did play it on speed 3 without pausing, so MP conditions, I only used pause when through some bad luck Aragon AND castille intervened in the reconquest of my vassals.
