Hi all! First (as this is my 1st post here) thanks to everyone involved in the development of this great game. I am not normally a gamer but 0AD is a true pleasure. And my suggestion against infinite farming near СCs is the concept of land fertility (different areas of land have different levels of fertility determining harvesting speed). This is a bit similar to de-bonusing but is this case land quality is a "primary" factor. You don't normally build a CC or something on fertile lands if their amount is limited. Land could also lose its fertility near some types of buildings. Now we can farm on almost any flat land with equal success but on some maps (desert/snowy) this looks a bit strange. Making good lands more limited resource could also add more realism to these maps.
