With increasing amounts of improvements available for construction, I think it is inevitable that there should be an option to build MORE THAN ONE improvement per tile. Graphically it CAN be made so that the graphics don´t look bad when there are multiple improvements per tile, already some of Civ 4´s graphics wouldn´t look too bad if there were for example a farm and a village in the same tile, it´s just a question of arranging the graphics so that they don´t overlap. Realistically there could easily be more than one improvement per tile, the tiles represent huge land masses and could easily contain for example a farm and a workshop or a village. With more and more improvements available it´s impossible to choose which ones to build and usually you just build the traditional farms for food and mines for resources, so with one improvement per tile you just use a small part of the available spectrum. I believe that the amount of improvements should be made MODDABLE, so you can choose how many improvements you can build on a tile. The graphics would have to be modified to adapt to multiple improvements of course, but the designers could take this into consideration and make the graphics as non-overlapping as possible. In my opinion there could be perhaps two or three improvements per hex (as many as graphics will allow) plus roads. A "land intensive" improvement like farm would be the PRIMARY improvement and others would be SECONDARY or TERTIARY improvements in addition to the farm. Those secondary improvements could be smaller improvements that don´t take that much space, like a village or mine or windmill or workshop. The farm paints the entire hex with farmland and on top of the farmland there is space for maybe one or two improvements, so that the graphics don´t look bad. Here is my case for multiple improvements, now I´ll put it to a vote, what do the people say? CHEERS !
