I was going to add least favorite, but that would have undoubtedly gone bad.

My favorites have to be the Japanese culture, and the Ancient Greek Culture.

Japanese culture because, I don't know, America has no culture, so seeing how deep their past is, beautiful places, and pretty women got me in.

The Ancient Greek culture because I love their mythology, it is just awesome.
Plus, if war was anything like the Samurai or ancient greek wars, I would definitely be in.
