Speaking about achievements, it's pretty much impossible to get the Big Entente achievement due to the ridiculous Peace Conferences. Yeah, so you somehow got enough warscore to annex 90% of Germany in the first round of the conference? Well screw you, your allies just released Germany as a democratic nation (not even a friggin puppet) with a single province, which will never join your stupid Entente because there's the allies too. Also Belgium takes all of Poland. And Memel.
But luckily annexing big parts Germany will give you that much WT that the Allies eventually will DoW you. I completed the achievement after conquering first Germany and Italy. UK released Thuringia as German Republic which joined Allies in an instant.
In a second war I manged to defeat UK and the USA somewhat in the early 50's... The Chanel coast from Brittany to Belgium was a nuclear wasteland (I didn't care much) as was California and wide parts of the northern USA (I approached from the south through British Mexico). All across Europe I had ICBMs stationed ready to fly to New York every now and then...
All just to annex Thuringia... But I stayed democratic the whole time.

I ignored the USSR as they ignored me. They were at war with the Allies from the early 40's, though. I _love_ ahistorical mode
It was a very tedious, but very funny game
/edit: Sry for OT. It just came over me...
