Alternative favor systems

[Birkaland]

The player have one Shrine. It can create invisible units with limited lifespan. They are called as sacrifices. The invisible units autogather favor.
There are more types of these invisible units, they have different stats. These stats can be modified by techs.
The Shrine build limit and the long training time of invisible units protect against favor overproduction.

 

I would like to hear more ideas.

give tributes to gods in form of food or gold to receive favour. (kind of like the market)
