Just completed a game of Gods of Old for the first time, won a religious victory. Thought it was a really nice tweak to the main game and I greatly enjoyed it. As ever with things I love, I'm motivated to point out problems and potential improvements:
Problems:
1) As already pointed out, the AI won't found Utu
2) The AI wastes catastrophes on An-worshipping civilizations
3) The AI goes crazy for building inquisitors. Non-state religions are often good things, and it just seems a big waste of production for the AI to be spending so many hammers on them.
4) It seems strange that missionaries can't be be built without Organized Religion after Scientific Method. I mean, gods are such an important part of this mod, I think missionaries should always be available, especially with all these inquisitors about. In my game cities in certain civs regularly became devoid of any religious belief at all because of over-zealous inquisitor activity.
Suggested Improvements:
1) The gods of this mod are supposed to be jealous and intent on becoming number one right? But at the moment I have no incentive to suppress other religions (except the holy shrine, and even then only at the last moment). I think it would be great if having a non-state religion caused an unhappiness penalty and maybe a culture penalty in its city. Also, I think you should only get great prophet bonuses for temples which are of your state religion. That way I have an incentive to suppress rival religions throughout the game, instead of at the final moment if I decide to go for a religious victory. Needless to say, this would mean the AI enthusiasm for inquisitors would be justified.
2) I think to win a religious victory, in addition to destroying all other holy cities, you should also have to make your religion cover like 70% of the world's population or something like that, just to give a greater sense that your religion is number 1.
3) It would be great if someone made a mod like this for the normal world religions. But I know that would be very controversial so it would have to be entirely unofficial
. The problem with ancient pagan gods is that they weren't actually very jealous and their worshippers were perfectly happy with worship of other gods.
