Unit Upgrade cost Broken?

[Daniel D]

The problem is that just before you research Iron Working, you should buy as many warriors as you can in all your cities and then upgrade them a few turns later. This is cheaper than just buying legions afterwards.

So your problem here is that a strategy game is rewarding a player for planning ahead and executing a plan instead of just throwing money at a problem at the last minute? Yeesh...

Then there's the issue that you need to have all that iron hooked up (or traded for) so you can support your warrior -> swordsmen rush buy.
