Cool stuff-but won't the mention of terror bombing give you some trouble with the PI forums?
I don't understand, why would it be a problem? It was a bombing, just like all the other horrible events that happened. This historical event tells a lot about dissent and relations between the countries, nothing more.
Otherwise, it would be really a cynical thing to play, for example, with Japan and lead all those armies which did what they did, but pretend that it didn't happen, and it is only a game of chess.
The important thing about this war, as well as all the others, is to convey the message and the truth so that they wouldn't happen again, and not romanticize these events through any game.
