I've noticed tribes having multiple settlements, but also there being multiple tribes with the same color. This can get reeaallyy confusing. Could you look into making sure maskling tribes can't have the same color? Or if they do they're all one big group?
Side note (When modding how do you make a race that auto-gens and isn't just created by you playing it? Is that in the javascript file?)
AI Tribes pick randomly from the available colors, sometimes there just aren't enough to go around.
During world generation AI tribes are placed, those are defined in the XML files. "wg_ai_placement.xml" in BaseMod defines the placement of the masklings. The ai_placement element defines what biomes the tribe will prefer, what territory size they'll prefer, and what javascript functions to use for generation and ai. I'm not sure how well multiple races will work, I haven't had a chance to test that yet.
A Viking race of high-health beings that come and raid your settlement, destroying a few buildings in the process.
Also, if you were to add some kind of upgrade tree for towers and archers, where they could either get better, or be fire archers, would be cool. The fire archers could do massive damage to ships and wagons, as well as structures.
Since the map has edges, I think it would be cool to spawn them from there. You could have raiders as well as trade caravans. For traders, you could require a special trade outpost building only available once you've made contact. They could be like the Harrapan trade settlements in Sumer.
As for the raiders, you could step up the raids as the map becomes cleared of barbarian tribes, or some other metric of game progression. Maybe they could even try to form their own colonies in addition to capturing yours.
