In short, what I was trying to get across is that I think there’s room in Civ 5 for a tile improvement (apart from the manufactory) that adds hammers to a (particularly non-riverside) grassland or plains tile. (I’d like to see riverside grassland or plains tiles meanwhile have the option of having watermill improvements built on them, as I mentioned in my earlier post.) That way, the civver has the choice of adding food (via a farm), gold (via a trading post) or hammers (via what I’ve called a windmill) to these tiles. .
That I disagree with. The limitation of terrain is important.
I'd would probably be better to not allow trading posts on hills.... but allow farms on All hills...
So hills would be
Food/Production
Forests would be
Production/Gold
Flatland would be
Gold/Food
I guess +2 hammers for mines is probably OK early game, because those hills require 2 excess food
2 Food->4 Hammers... is the same as a Forest with a Lumbermill (1 food->2 Hammers)
4 Hammers could then be
1 Mine+2 Farms
2 Mills+2 Farms
4 Plains farms
The Mine is better for Happiness
Eventually (with Fertilizer, Steam Power, etc.) it is 12 Hammers through
3 Mines+3 Farms
4 Mills+2 Farms
2 Mines+4 Plains Farms
3 Mills+3 Plains Farms
And all are the same for Happiness
The Gold-Hammer balance is interesting because Buildings and units compete for Both.
BUT
Gold+Units are Imperial, Production+Buildings are local
So a Hammer can be spent
1. On a unit built here to move throughout the empire
2. On a Building Here.
Gold can be spent in so many other ways
1. On Unit/Building/Improvement maintenance.... ONLY Gold can do this
2. On Units/Buildings anywhere in the empire..replacing Hammers
3. On City States
Actually, an idea for making Railroads Really useful, ditch the 50% bonus, instead... if a city is connected by rail to the Capital, it can "Build" ie Send Hammers to the Capital and the Capital can "Build" ie Send Hammers to it. (this could be limited to Buildings/Units, and the Capital couldn't 'send' to a city that was sending to it) But it would make Hammers>Gold because they can be Delocalized.
So the default would be all cities Building theire buildings, then sending excess to the capital, which sends it out to cities that are still building, or cities that are building units.
That way Buildings could be put up fast.
(It couldn't go to Courthouses, or to/from Puppet Cities)
Somne wonders could stand a boost as well... (Pyramids being +100% worker action or +50% worker action and +1 Worker movement might be good)
