There're to facts which made me get this ideas:
It And it doesn't look like a granary, it looks completely like a temple. So, what has a temple to do with gold, wood and food? Well, what do u think this building could be?
It could be a temple where villagers store these 3 ressources which creates favor.But as we know that the greeks don't get their favor in this way I doubt it.
It could be like a relic in a monastry:
ie: after 2 mins you get 5 wood, after 2 more mins 5 gold, after 2 more mins 2 food ect
Maybe you can store the 3 res. there , but you can't use them.(ie: you have already 200 food, you store 5 more food there, but you still have 200 food (not 205))
In the fourth age you get a GP which makes that you get twice the amount of the res. you stored in the building.
(ie: you stored 500wood and 50 gold, and the GP(u can only use it if u have this temple) gives you 1000wood and 100 gold then)
You can create a res. gathering MU there which only can store its res. there, but I doubt it.
It really looks like a temple and does store res.
