Hello.
I think it's better to make victory condition "
Alter of the Luonnotar" to
victory for Researchers, like Space Race Victory of Original Civ4.
in particular, my ideas are:
1)
"Omniscience" technology requires "Divine Essence" technology.
Then it requires "Divine Essence, and Commune with Natures, and (Strength the Will or Pass through the Ether)".
If it's too complexed, then "Divine Essence, and (Strength the Will or Pass through the Ether)" is also good.
2) To
reduce the cost of "Alter of the Luonnotar (Final)" to 2500

or 2000

. (now it's 4000).
Or, here is another idea, the cost of Alter(Final) is 4000, but
Double Production from Mithril.
I think that "Divine Essence" is very useful (or required) to make the altar for the one true god.
"Divine Essence" is at quite different position from "Omniscience" in the tech tree, so you have to research very hard to acquire Omniscience (literally).
Instead, to build the Alter(Final) becomes a little easier.
Now your civ needs more

instead of

.
Which victory condition is suitable for each civilization ?
- Conquest and Domination Victory - for

Aggressive Civilization
- Religilus and Cultural Victory - for

Peaceful and cultural Civilization
- Tower of Mastery Victory - Balanced (Warfare and Research)
then, It may fits.
- Alter of Luonnotar Victory - for

Scientific Civilization
