Ok, I played a California Republic 2.1 game last night.
THANK YOU for adjusting the population levels.
1. California has cores on a couple Baja California provinces, but no CB.
2. California has no event/decision to form the Western States. Why not?!?
3. Federal States is OP. They should not be as strong as they are. We're talking about a world where the US has been balkanized. It makes no sense for so many states to be like "well, we hated Federalism the first two times, shit lets try again!". So I'd suggest nerfing the Federal States rebels, and restricting cores when the Federal States does emerge. Maybe only adjacent territories so it doesn't blob uncontrollably across the continent.
