One thing I hope for is a rudimentary POP system, rather than just the vague concept of "manpower". Now, this would of course be much simpler than Victoria 2's, but still I think it could add a lot to the game. For instance, have a "merchant" class, perhaps, that ties into trading. Or a "serf" class (Depending on policies, Native American tribes as well as others did not have such systems) that works the land. This would also allow for more than one culture and one religion per province. This would solve the problem of having provinces suddenly flip from one religion to yours and instantly becoming useful. Anyway, that's my take on it, and I'd like some other opinions.
