I have fond memories of this one. As far as RTS games go, it had a fairly complex economy and you couldn't just spawn giant armies because you had train peasants into soldiers. It has a great Medieval Japanese theme too. SO if you're down for some old school unique RTS gaming, check it out!

I remember this, it was a pretty neat RTS back at the older days.
Reminded me a lot of the older Warwind series (you buy a lowly peasant and train him in various buildings to make him a certain unit).
