I've overlooked these for too long I think. I've been playing different civs than my usual just to see if there are any suprises and this was one of them. The power in them is that they turn production tiles (+2 hammers) into farms without losing the production. So all those hills become +2 food +2 hammers min, more if next to a mountain and even more with fertilizer. It really is quite powerful for science where you need both high population and production.
Anyone got any other civs they would recommend I give a look at, and why?
