I have bought the majority of the necessary improvements and i am down to 3: Guerilla camps (not unless im at war) border walls (probably too much pop for it to be beneficial) and labor camps.
At what point are labor camps worth buying? My current infra upkeep $653.76.
no because, even though i cant buy level 9s yet and before, i could, planes are very destructive when in full force level nines and only very strong nations should be able to have a full fleet airforce.
