Here's a random stealth action game that has never seen a US release.
Made by ex-Tenchu devs it shares a lot with their original work but takes the genre in an unusual direction. The main gimmick is a dynamic campaign in which three feudal lords try to take control of a small province. The player is free to choose clients and missions and complete them or fail them without the whole world collapsing. There are a few other gameplay mechanics in addition to sneaking around but we'll get to them later.
Shinobido's major problem is repetitiveness, so we'll have to make our own fun.
