Aabraxan said:But I won't be penalized on the resource (other than by not having it irrigated), right? By way of comparison, I think in SMAC, if I build a mine and a farm on the same tile, I get a -1 food penalty for the mine. If I can't irrigate and maximize the food, I don't want to further cripple my food production by building a mine if that's the effect.
For the sum total of food/shields of your city it does not matter which tiles you irrigate and which you mine. An irrigation will always give you one more food, regardless where. A mine on flat terrain will always give you one more shield, regardless of where. OK, except for despotism.
(Oh, and there is an other exception, and that is a GA or mobilization where an irrigated tile without an inherent shield will give you no shields at all while a mine would give you two.)
