Baller. I'm currently mentally prepping for the tier system rewrite. Basically as I see it each country should have 3 tiers with unique bonuses at each level - which is a lot of individual decisions to make.

I think I want to merge the development system with the tiers system, and I think I might want to have rather than static lasting +'s/-'s to development to do with more of an 'equilibrium' system. So France's equilibrium for development is tier 2; if it's above that it'll slowly fall and if it's below that it'll slowly rise. If a positive tech is introduced or an agent is deployed then that equilibrium shifts up.
