Excuse me, old bean, as I know old Attacko may have quite to many things on his hands already now, sir, but I am under the impression, sir, that I have found, in a sudden flash of realization, your arguments do not hold water! Quite inappropriate as it is for me to be so rash, as I know I should not rate as high as these alleged players you have discussed such things with, I believe I have, with some certainty, released something of a flood of errors!
Your first explanation makes very little sense, if I may say so. For a start, old bean, GPG has nothing to do with the influences of civilizations other than oneselve's. Nor will trade agreements, unless the resource in question is harvested only from the razed city, be thrown into turmoil. Surrounding units will have something of a small mutiny in the wake of the city, of which they were to reinforce, of such's razing. Though this is quite a point, my lad, it does not constitute a full game strategy.
True, that razing cities gets gold, and you need not slow down to defend it. However, in my belief, if the city has infrastructure, or even Wonders, if one is lucky, one should keep it. Razing after capturing does not give you any gold, old boy, and science cannot be affected by it, old bean, outside of random events. But good try, lad, good try.
You do, my boy, have a small point in that the unhappy citizens does not affect you with your own cities, and for this I applaud you. However, it must be said that this is a well known fact, especially amongst veteran fanatics, and needs not be posted.
It may be true that hills are easy to defend, however hills ought be for mining, if you ask me and many old boys in our ranks. It matters not, to me or, I would assume, to many other Fanatics, whether towns are easier to look at. Hills are given a natural power of production, old bean, you ought use it! Mine the hills, and you shall be all the richer for it. Cottage riverside flatlands, mine hills, and farm lakesides, and all should be well, old bean.
My! What an outburst! I should say I need a cup of good Earl Grey. Thank you for your time, old chap.
