EmpireOfCats
Death to Giant Robots
If someone is fluent in German, perhaps will be able to analyze this video a bit better. It's in a really good quality and zoomed in, so there are a lot of data about combat odds, promotions and such.
I can just help a bit with what the guy with the mike is saying: He likes the combat system, but not the social policies because you can't change them once you have picked them, which he says is "unrealistic". Other than that, he likes and is going to spend many a night playing Civ V.
Somebody else is going to have to analyze the video, I'm afraid.
