I Cant decide between Medieval 3 and Shogun 3.
To Me Shogun 2 is and always will be with all these new dlc's the best Total War game, i love all the others besides Empire coz i never played it and a 3rd Shogun while it would be abit to soon due to it being the last 1 out before Rome 2 it would be so amazing still.
But...
Medieval 2 was also a very fun game and i believe if they bring both Medieval and Shogun together not act together i mean take things from Shogun and implement them into Medieval and any other total war game if im honest.
