idea for an expansion pack. Deities(yeah yeah i know)
ok i know that this has been brought up a few times, but i think this could be an interesting game mechanic.
i think that this could be implemented by having a set number of deities, good, evil, neutral. the way it would work would be you make offerings to them, or do something for them(special quests, declare war on a certain faction etc.) and you gain favor points. this points can be spent for certain favors from the deity you offer patronage to. this could be any one you wish, this is not something you start the game with or anything. example.
you have just declared war on gilden in the name of the wargod Sardis. each time you fight a battle AND win against gilden you receive some favor points with sardis. after gaining 50 favor points you offer the prayer of the warlord(which costs 50 points). Sardis then sends you a powerful Juggernaut unit.
you could cast those cosmetic spells and create flowers everywhere and gain the favor of the nature goddess and she could grant you a special food tile to build on. giving a very high food bonus.
the possibilities are endless.
of course if stardock isn't interested this could be a very interesting mod to make that would mostly just require code and a few art assets.
