This isn't a hate thing but more of an historical inaccuracy the game has or if not someone please correct me.
The foreigners looks are British right? I just don't really understand why are they talking about them as the foreigners when the Dutch with few Spanish traders from the Philippines and American people where much more prevalent during that time. The Dutch even founded Nagasaki just saying.
I'm not really sure but I also think the British didn't have much contact with Japan until the Anglo-Japanese alliance that happened around 50 years later.
I'm not trying to say the British shouldn't be there just saying its rather weird having them during that time period.
