At 1300 hours just playing Shogun 2, I can wholeheartedly agree that I could not stop playing it. I've never modded it.

I just played in rotation, a ROTS campaign, then S2, then FOTS, rinse repeat, each has it's own interesting aspects for me.

While I've been on a bit of a break lately as I played a couple campaigns in Rome 2 that were quite time consuming affairs, and more recently I've been completely sucked into the world of MTW2, which I never played when it initially released, I know eventually I will play yet more Shogun 2.

Everyone has their favorites, I doubt I will ever love anything as much as I do Shogun 2 and MTW2 (I can't wait to see what EB2 ends up like).

And yes Gregoshi, I would definitely recommend picking up FOTS at the next sale, it is just so much fun. And as Alcibiade makes mention, the realm divide is vastly different than in the other two variants of S2/ROTS.
