So when the Teppo or Archers run out of ammunition, do their combat stats change dramatically? I'm curious since once overrun, they were forced to hand to hand fighting. Of course the mounted archer units would be armed samurai, so they would be switching off to yari or katana.

What's the Benny Hill effect? I know the English comedian.

My library is in storage. I don't recall if Turnball explained if Teppo were available unless you had access to Portuguese traders. If the only way to get them was constructing Cathedrals, it seems like having the ability to create warrior monks and Portuguese teppo is unfair.

I'll bet that the rifling wasn't present inside off the barrels (the long spiral that guides the ball), but they still would have been somewhat accurate at close range. I doubt that the samurai would let just anyone get access to the matchlocks, particularly peasants. They were probably poor farmer-samurai ashigaru who got upgraded instead. It would have been dangerous to allow commoners weapons, hence the banning of weapons in Okinawa.

What program do you use to edit the source code? Are there programs so that you can change rules on the fly, or make additions?
