Thanks for all the kind words, glad the unit is working out for everyone. I like the sound of a jet for every civ, but I too am lost past germany and england. Seems to me that the first US jet fighters, the ones used in korea, (though I don't remeber their designation) were in fact copied in many ways from the Me262. I could be wrong, but I remember reading that after the war ended in Europe, the US government shipped a number of Me262s back to the US so they could study them and try to reproduce them.
As for units for other civs, I'm currently working on one for the Americans, though I doubt it'll be very popular--it's an atomic bomber, modeled after the B29. It'll basicly be a nuclear missle that will be american only, available in the industrial age. As usual with my units, I'm making it with an earthmap in mind, so it would no doubt be too powerful for a regular game. Oh yes, I'm using the standard "zeb's earth" map, because it's asthetically pleasing, and the enormous maps are just too much of a pain for me, so on Marla's map, if you all play on that one, most of my units would still be unbalancing.
