also does this neighborhood cost apply to kongo, cuz if so massive penalty

why r neighborhood so expensive

does the cost increase with # of districts built or placed?

they are just changes to base values so they scale with speed

Does the value differ by the game speed or are they kept the same?

it should.

Is it working with New Frontier Pass?

I have played a few games with the mod and find build times to be fine. What do you mean buildings are not worth constructing? If buildings are very fast to build, then you get the problem of quickly running out of stuff to build due to district limit (apart from pumping units). If you thing buildings are barely worth building then maybe a mod making buildings better would be the answer.

building cost was originally based on when it unlocks instead of power to ensure that building times roughly follow your increasing production throughout the game. Temples are cheaper than factories because by the time you unlock a temple you have much fewer production than by the time you unlock a factory. It's part of the core gameplay loop.

Buildings already struggle from barely being worthy of constructing. I like the approach of tuning down district cost, but the changes to buildings don't seem supportive of a smooth gameplay experience at all and kind of counteract the original purpose of keeping production cost reasonable.

Temples take 250 production, like all tier 2 buildings. Unmodded temple takes 120 production to build. So it is correct that build time is doubled in the casse of the temple.

Temple is quite cheap in the unmodded game because it unlocks early (clasical era) compared to the other tier 2 buildings, like the university and bank. I don't think that cost should depend on when it is unlocked, but on how good it is. And the temple is on par with other tier 2 buildings, so therefore should cost similarly.

Maybe its a mod conflict or something, but this drastically increases how long my temple buildings take to complete
