Today, I finally got around to finishing up the Samurai campaign on Realistic difficulty.

The ending scenes played and credits rolled, but no rewards at all. No fancy ornaments for me I suppose.

As I have already played through the entire story line on Normal previously I just went back and replayed all the missions on Realistic.
I obtained the rewards for Realistic difficulty for the Knights AND the Vikings, but when I finish off the Samurai missions? Zilch. Nada. Whats up with that?
