Why waiting until certain tech before war option will not work

Actually you *can* set peace to be based on time instead of age. Current increments are 2, 5, 10, 15, 20, and 30 minutes.

Re: upgrade costs - there are two factors here, the cost of the units and the cost of the research. The cost to actually press the upgrade button is the cost of the research PLUS the difference in cost of the units being upgraded (if there is a difference). This means that you cannot buy a bunch of cheap units in the early game and "bank" them for an inexpensive jump to a late-game unit. On the other hand, if you progress several ages before you research an upgrade, you can avoid the research costs of the intermediate upgrades. This isn't really a huge savings and is more than balanced by the player having understrength units in play. The research costs are fairly reasonable - its upgrading a ton of units that can end up costing a lot of resources (and rightfully so).

Thanks, but... 30 is max?
