I have played this game several times over the years, and "now" I am "forgetting" how to get the God Powers.
It's taken "forever", 3 days, to get the God Power "rain", the one after the bloom Power.
Are they "earned" by population? or tech points?
Still am "enjoying" the game after all these years.
Can't "wait" til I get VV4 "again."
GBU and yours.

There's a sticky thread with a lot of discussion about the God Powers. This part of the discussion should help you.
