We are nearing the deadline to Gods and kings as we come closer to April. I have been looking for some more information and I hope these quotes shall help you in your understanding.
Beach: I think what was engaging about the Civ IV system was just the idea of religions springing up and spreading throughout the map, bumping up against each other, and there being conflict there—wrestling for control of the hearts and minds of everybody. That gave a great flavor to everything, and it felt like it was a richer world because of that, but taking a hard look at that, we didn’t feel like there was a huge impact on the gameplay. It was like this cooler world going on, but it wasn’t really giving us interesting decisions, so we kept some of those neat immersive things about it, but added how it loops into the gameplay.
PCG: Do the religions–Christianity, Buddhism, and the others–come with existing beliefs? Can they be modded?
Beach: We have one scenario that’s set in the Middle Ages and the Renaissance, where we actually do pre-bake in beliefs, and that’s a great example for our community about how the religion system can be modded. What they can do is add more beliefs in. We have a good set—there are between 50 and 60 beliefs that will ship with the expansions, but there’s no reason the mod community can’t expand on that.
But yeah, the historical religions are just sort of like containers that the beliefs get slotted into–there’s no reason that guruship doesn’t have to be part of Sikhism or Christianity.
So as you can see religion is a big HIT in this expansion pack
One of the bigger changes that will happen with Gods & Kings is a serious revamp to the combat mechanic. Previously, units had roughly a 10 point system to work with in terms damage and health, making combat move pretty darn fast. Gods & Kings brings a 100 point system that can slow down battles, giving players more time to form combat lines or retreat effectively. That’s a huge difference compared to the approach (turtle with units and then perform a blanket attack across the map) most used in Civilization V.
I hope this information was helpfull
