I have gone back and forth on releasing the hard numbers for how much stuff costs, and I do see why it seems fair to let you know them. However, I also worry about people figuring out how best to game the formulas and increase their income fairly rapidly (which would be fairly easy to do). This would only give the rich nations an even greater advantage than they already had.
I say: Give numbers for specific questions. If we want to build the
Gothard Tunnel, for example (actual construction started 1871) it would be ok to give us an estimate of the costs in money units, with the usual caveat that actual costs may be higher. Or if I want to recruit 10,000 soldiers, I would have a fairly good idea of what it'll cost me, so I should be able to ask Perth.
