Ya, these would defiantly be options for human only games. Hopefully in the near future, a network game play can be implemented.
And another thought on Nukes, as in Civ III (I think), do not allow them built until Manhattan Project, but in addition don't allow their use until the end of the Cold War, to allow other nations time to build their own or properly defend (with missile defense or global defense like satellites).
As for civics, I like it because of the greater control over your nation's type.
Global change would mostly just cause riots and population decline, or at least reduce the productivity of all tiles (slowly over time or there would be no chance!)
