I just now briefly thought about trying to do/write some of what I recommended above, but then I remembered that I can't, because I'm not in a game at the moment, and because even if I was, there might be differences in the Eastern, Western, and European early-game unit/building/research costs - And, even if I was in a game right now, it would be hard to recall what my day 1 resources and production were.
Then I wished (again) for an improved Wiki that would include the information I would need.
Then I decided that investing any time in this would have to wait until the start of my next game.
But maybe I don't have to wait - Do any of you alliance or solo players both have the raw material I need, and care to share it?
I'm not asking for your secret Day 1 strategies - Just for the raw data that describes a typical 5-city or 6-city opening position (resource/cash stockpiles, resource production/income) , and describes the costs and production/research times for basic units and buildings?
