Quoting joasoze, reply 5The bad thing here is that I see nothing in the game that stops infinite city spamming
Well, for one, on a finite sized map, there is only so much space in which to build these cities. It also means, you have to put more into defending those cities, so that's more resources tied up. You also may spread yourself thin, which means those cities are more vulnerable to being taken over...
I know you folks listen to us. I know we had a _lot_ of good discussions in beta regarding avoiding city spam (some of the SD devs chimed in stating that was a major goal), we discussed a number of ways to limit it. The allowable distance between cities was increased during beta as one method, and increasing cost for successive cities another.
Increasing cost for successive cities was removed, it appears only a small minimum distance between cities now limits city spam (especially if the AI cheats resource-wise).
The game now rewards spamming cities (control of land and resources, multiple buildings to produce research/materials/gold/etc., etc.). The game does not reward having a few but large and well-developed cities. A good strategy game would have both be viable options.
