Thank you Kinobat! They're great.
I'm using them in my HPM as flavor units, as follows:
Ashigaru - Pikeman
Bushi - Swordsman
Kensai - Medieval Infantry
Samurai Archer - Archer
Samurai Spearman - Spearman
I have civilopedia entries for most of them, if anybody's interested. They might not be 100% accurate, but we're talking about an Atari game after all.
I know that you've just done the Samurai Archer, but could you please make a slightly more advanced unit, like one with a crossbow or something. I'm sure some existed. The Chinese had crossbows as well as the Europeans. Then we would have the Japanese Worker, Settler, Spearman, Archer, Swordsman, Longbowman, Pikeman, AND Medieval infantry all done!!
