I'm not eager to play naval battles, I'll limit my experience here, I'll just use navy to protect my borders and so on. Is looking good, sure, but I just don't feel that naval battles were so important for that period. after all, the race for shogun was played on the soil.

I liked the naval battles in Empire/Napolen Total War because of the period and teh historical set up.

I like that ninjas will not be that good during the day, that's fair enough. should be slaughtered easily in the open field.

Now back to the naval battles I have the feeling that SEGA will produce a DLC with invasion of Korea. Doesn't have sense such a polished naval battle part of the game, only for Sengoku
