A close second with Shogun but those two are both amazing , especially FOTS
I actually liked the standard Shogun 2 more. I wasn't a big fan of FOTS, mainly due to the amount of gunpowder units. I liked the more classic battles with Archers, Yaris, Naginatas & Katanas. Doesn't mean I didn't like it, FOTS was great but basegame Shogun 2 is the best TW ever made.
