is Shogun 2 turn based or RTS ?
never played it.
It's Both. You start as a local lord, in charge of a province or two, and you scheme, plot, assassinate, and try to conquer all of japan. The battles you engage in are realtime, so you can assemble some rather impressive land and naval battles.
Elevation, morale, exhaustion level, and type of unit all factor in. The one thing I haven't figured out how to do in the this version is predefine army formations (like archers take the hilltops, heavy cavalry on the flanks, firearms and archer rotating, spearmen protecting against enemy cavalry). The first game had preset formations, like "flying crane" and stuff. Pretty fun game, and they have others in the Total War series set in other time periods, like Medieval, Rome, Napolean.
