Thank you so much for the quick and expert advice. Ive played... over 1000 hours or so but havent spent any time doing editing myself. Just exploring and enjoying others creations. This game is so wonderful and the mod community brings out infinite depth of play. So, this is the tetturkans test of time with cities scenario. Most of the modern big build items like battleships (10,000ish) and jetfighters (2280)are all set to be very expensive. However the modern armor (560) is only a little more than the old armor (150)and is far overpowered to any other ground unit including mech inf. (280). I worry about them being mass produced and then ground warfare becomes only columns of tanks. I do not enjoy when warfare just becomes who can produce the most of one unit/a single unit arms race. In the past it's what this scenario has become st the end of the modern era. So I was going to bring it up to 1500 or 2000 for modern armor. I think this better reflects real world cost of production and availability compared with the other high value units in the game. I will get the new civeditor.
Which brings me to my second question. Is it possible to edit a game that is already running? How can i make an edit effect a Sav. File? Or can I only use this for the next game I start in this scenario?
