Well yes, but we - especially you - continue to work in it. That will not change if we also give "Upkeep" a try. Then why don't we just give it a try. I could do the implementation, then we balance and improve it internally and then we publish a beta to get feedback for fine-tuning. If we apply "Upkeep" just during War it will become too easy to exploit again and will not really help AI. You could still build up a huge military and navy without consequences, then rush AI and conquer its cities. This might need only five turns and thus cost you only little Upkeep. Then you could declare peace again and prepare rushing the next AI without any Upkeep in the meantime. So please - if we implement Upkeep at all - then let us not limit it for "War" times only. The Wars themselves are over too fast if you prepared well. The preparation of your army and navy needs to also cost Upkeep already. But we could have "increased Upkeep" during War - e.g. 20%. (That would be configurable in XML of course as well.) But ok, let us wait for more feedback and ideas.
