Ships in the new game (Shogun2) looks graphically less refined than the old game (ETW/NTW). Some people say: 'the first screenshots, so no wonder'. Remember that the first screenshots are always in the best detail to impress the players. Why CA presented such an ugly ship in first screen? Look at the items I pointed out in red. The ship is made from solids inaccurate. The model is very edgy and drawn on the texture, for example, only the green bamboo.
Compare the screenshots of the Empire shown two years before the released.
