"Thematic", no no it isn't, when you're already being allowed nuclear fission power and a semi-underwater city/island nation state.
Yeah, you're right. I won't push.
Anyway, I've read that you accept suggestions for the cost of the custom trait? I 've been waiting to add these trait to AI, so here's my suggestion on the cost
Fuhrerprinzip/Glorius Leader(+2): This trait give any nation a weak point that anyone can exploit via assasins. While ditactorship and monarchy kind type gain should popularity an unity boost from this, their nation would fall apart quicker if the guy/gal was killed.
No Gods, Only Man(+4): Any religious nation will be out for your blood if you choose this, and even neutral nations will like you less because their religious communities will by denouncing you. Not to mention the revolt risk and the stunt on cultural growth and poor spiritual lives of your citizen(If you use tropico logic, this trait should give a boost to science, so take it down to +3).
Self Sufficient(-3): While normally a mediocre trait, this is a lifesaver in an ISOT situation.
Orwellian Police State(-5); Stomping down on social unrest and help defense again outside espionage? Why doesn't everyone have this?Though this may increase the number of people turning into rebel if they are not caught.
Minority Rule (+1) This should also increase the amount of rebel you may have on your hand as well as how fast they can convert other citizen into their cause. you should get a boost depend on who get special treatment and how many group are there. (For example, big boost to science if only intelectual get special treatment, but mediocre boost to science and economy if both intelectual and the wealthy get special treatment)
These are just based on what I think sound right though.
