Thanks.
I've never been in favour myself of stuffing cities full of units due to paranoia - those units could be used better elsewhere, or not built at all

. The only time I've been guilty of this is when there is one city guarding the only viable land route (ie RW Istanbul, Suez, Panama etc) or when the city is right on the border of a highly agressive rival. Normally, each city will have a garrison of 2 defenders, a fighter if on the border, a patrol boat if coastal. If I feeling very generous, it will get another defender. The rest of my troops would be hiding out of sight.
I do build civil defence in all my cities - but they are not my 1st pirority (unless war is looming and I know I will be outnumbered) In peace, prepare for war. However, my people get some butter with their guns.
Well, you have helped me notice a very bad habit that I have got into. For a long time, I played PTW which had no flaks, so I built SAM's. From now on, I will build far less SAM's and a few more flaks. What did I think was going to happen? Air raid on a city 20+ squares behind the border? I doubt many Humans would do that, let alone the AI.
Yeah, fighters are just recon planes which just happen to be armed. I was so dissapointed with them when I built them for the first time in war (I had built 20!)
In most games, I'm Communist. I will only be Democratic if I have enough things to make 'em happy. By around Invention, I know what gov I will need, and will beeline accordingly.
One question - factories, power plants and pollution. When do you start to industrialize? Do you change all the build orders for them? And what power plants do you hook up at first (if any)? And what is your first pirority - whack-a-mole the pollution or build your railway network?
