I tend to run Rokugan with a bit more detail and I have leaned rather heavily on actual Japanese history to help fill in those small details. I've discovered the Samurai Podcast that covers at lot of different subjects. I'm currently listening to a discussion on military formation sizes. But it covers a lot of different subjects from mundane to supernatural which may be of interest

Thanks! I'll probably still wait for your awesome breakdowns and posts (which I've totally never stolen for my own purposes, not once) but this seems like a cool podcast.

I listen to these guys! I just got done with their episode on Seppuku

Wow, what a find. Thank you! Finish listening to their Seppuku episode this afternoon. IMK, very fascinating; I love the amount of detail he goes into on the topic.

You should also check the SA forums (and the forum archive). Lots of information there.
