btw can I add more tech levels?
The editor is very flexible. It can do that.
While you can add more tech levels, there is considerable cost. In the Europe 1939 scenario, it costs 40 pp to get a Fighter II, 80 pp to get a Fighter III, and 160 pp to get a fighter IV. A cities worth of production is 5 pp per month. Upgrading to Fighter IV (or Light Tank IV) would consume the entire typical German monthly production in 1941. Note that powers also have to buy supply (takes roughly 25-33% of production normally, 50% during the winter) and units. Therefore, you have to carefully balance what you would upgrade vs other requirements. However, you could have many levels and also change the cost per level.
I have found that in Europe theater game, I normally get fighters to level 3 or 4, infantry and light tanks to level 2 or 3, artillery and divebombers to level 2 and have a couple of other upgrades.
