Yes .
Two things:vmxa said:No one said it because there is nothing optimal about CxxxxxC. It is just wasteful. The key points have been beat about many times.
You will not be able to use more than 12 tiles in that 21 tile city for most of the game. Should you ever get to the point of hospitals, it takes time to build them and fill the metro.
Wasting tiles is not 'optimal'. Stunting your city size in cases where you could otherwise support a larger city is not 'optimal'.Overstocking on defense is for losers, plain and simple. I leave that crap for Emperor or lower players. Overstocking on anything is not playing optimally, but you have already confessed that you do not play optimally.
AutomatedTeller said:That said - optimizing for metros is a perfectly reasonable style, and would be most useful once you get to the IA. I wonder if it is a more efficient way to play a space ship race game? certainly, fewer cities in the same space gives less corruption once all the tiles are used, plus less maintenance because of fewer buildings... hmm...
