When i can't grow any further? Given i have a happycap of 4 for example?
Well, whatever, i'll just take your word for it as you're a code digger or something alike. But stopping growth on size2 just to get the full advantage of the granary seems... Well, whatever. It's just that i have enough games, even on Deity, where happiness is rare and not tradeable until like 500 BC, but where i still want granaries to 2pop whip Axes/Swords, Workers etc just to regrow faster (and ofc for the time happiness is available to grow bigger faster). In those games, more food seems like pure waste that early as i can't grow very big anyway. Rather stagnate as fast as possible at size 3 or 4.
And when happiness is available i already have the granary and just work the food.
So ... wait with granaries until i have happiness? Seems wrong too. They are useful even with a low happy cap, or at least it seems so oO
