I don't know if there's a guide for this but hope there is... I'm currently deleting all the temples and using just 3 tree's - adding bonus's assigned to factions... so that I have more building space... that's been done... with the text file I haven't gone into great detail but just used the same description for all 3 (assigned to all cultures) that I can later add to... I changed descr_strat temples to the new building names...
My game doesn't run when I tried experimenting all this...
I did a quick look into what other files still use the vanilla temples;
data
descr ui buildings
export descr advise
export descr ancillaries
export descr character traits
export descr sounds advice
data/text
export_advice
Does anyone with more experience know which files exactly are needed to be altered for all this to work? I don't see how advice matters for making the game stop... character traits, I can barely understand how I'm going to affect the game here... and anchillaries I have changed as that one was easy.
I'm making this post because I don't know if it's just these files... whether it must be all of them or just a few... cheers.
