I played this at tier 1-2. This review does not contain spoilers.
The meat of the scenario is a resource-management minigame, which affects a village's readiness for a siege and mass battle. Unfortunately, given the racial and ethnic makeup of the average party of Avistanian PCs versus Shokuro villagers, what it amounts to narratively is Mighty Whitey swooping in and saving the bowing and grateful brown natives.
Seriously, this isn't a case of "the PCs are special and the villagers just happen to be brown." Not only do they turn over complete control of the village to you, to the point where you decide how many people will work the fields versus shoring up the defences, but mechanically, one PC can do the work of five villagers ... even when that work is harvesting rice. In an agricultural village where that is their livelihood. I thought Profession wasn't usable untrained?
It was when I realized this that I said, flat-out, "this is really racist," and the GM was like "yes, it is."
I tried to explain away some of the implications by saying that my PC (a kitsune shrine maiden of the goddess of rice) was performing a harvest ritual or something, while our half-orc fighter could do the work of ten farmhands just because of how strong he was. But it just seemed really unfortunate that these people had no agency and were being reduced to playing pieces ... which was a theme I felt like I had seen in the other Dragon Empires adventures, where the whole continent was exoticised and existed only for "western" people to have an adventure in.
Finally, it may just be that we aced the resource management part. But the epic battle some reviewers liked felt more like shooting fish in a barrel, because this overwhelming force seemed to attack in such tiny waves. I get the impression they were going for something like Dynasty Warriors, and I'm wondering if our GM was just having trouble describing the action.
