1. Nagashima should be in Ise, not Owari.
Changed it now, thanks.
2. In the diplomacy text, "Konnichiwa" and "~san" is too informal and modern... By the way Daimyos should call each other "(Family name or Political title)~dono".
Konnichiwa and ~san come from Civ4 (that's what Tokugawa says). If it's bad - OK, but if there's no replacement I can only use plain English instead.
I'll look at ~dono but it's unlikely to work because replies are universal, so if you were playing Ikki you'd see "Ikko-ikki-dono" / "Iga Sokoku Ikki-dono" or at best "Honganji-dono" / "Fujibayashi-dono" etc. I don't think these make sense (or do they?)
3. Wako shouldn't be used to refer to pirates in Japan. The modern term "Kaizoku" (Literary "Sea Bandit") was probably used back then.
Even if wasn't used back then, Wako seems to be used as a historiographic term in English texts, also when referring to pirates from around Kyushu and Inland Sea. It's a well known term at least, immediately recognizable, so I'd like to stick to it for the ships at least.
I noticed that as Oda I can grant cities to "Toyotomi Hideyoshi" as a vassal when "Hashiba Hideyoshi" is present, but Hashiba still remains in Oda and Toyotomi is newly created separately.
Also, Hideyoshi should be Hashiba until 1586.
Oops, that's fixed now, thanks. As for the name, it's not changed in a given year, but instead he changes his name when he receives or grabs land.
By the way, could you possibly make a victory condition aside "become Shogun"?
Most warlords wanted to "restore" the Ashikaga and some (like Nobunaga or Hideyoshi) wanted something else.
Well, Mori for was status quo, but I'm sure if Uesugi or Takeda got the point of controlling 1/3 of Japan including Kinai, they wouldn't stop at that. Also, Toyotomi probably wouldn't arrange himself to become Kampaku/Taiko, if he could legally become a shogun. So I think the mechanics cover more cases.
But if I was to add something else, how would the victory conditions differ from the current ones?
EDIT: One idea would be a Vassal Victory - win as a vassal of Ashikaga shogunate; this could be coupled with the possibility of giving Kyoto to the Ashikaga, then working to increase its Legitimacy. Ashikaga would get +25% bonus to Legitimacy from a trait. Does that make any sense?
Playing as a vassal can be annoying though, since you have no control over your wars.
