Apologies if this has been asked, but I couldn't immediately find an answer. What is the best option when faced with multiple options on a tile square. Irrigate or mine? (And why?) Personally I: Mountain - Mine Hills - Usually mine Desert - Usually mine unless there is little food in the city radius, then I might irrigate a few. Grassland and Plains - Irrigate And then the unusual squares: Forest - Usually leave Jungle and Swamp - convert to grassland Any other thoughts?
