I'm going to be doing what I hope will be a "community driven mod". With your input I will make changes and incorporate legends, stories, different samurai clan civs into the mod. Your greatest heroes who defeat megabeasts will join their ranks as spiritual gods, and the founders of the different clans. The civs will be modified to reflect play changes and items, weapons, armor, and friendliness to each other will change over time. Over 500 creatures have already been added, but not all are perfectly finished. I will be working on that with your input.
In an early test I played an adventurer who traveled to a Mongol forest town where the Koreans were defeated. There spawned so many forest creatures that the Mongols were constantly embattled by ghosts and forest demons. A bunch of fiery ghost/demon spirits spawned and wandered around, lighting the grass on fire, which quickly spread across the town- turning it into a hellish landscape with the guards battling spirits amidst the flames, with the townsfolk burning and lighting others on fire as they ran for safety. It was really cool but a bit overkill. I nerfed the amount of flame spirits and lowered their heat points.
