I like the replacing of units as time and tech evolve. This does part of what I always wanted to do, but would take a while, that is to say, start out at WW1 (or 2) and just keep playing until 1 side defeats the other, then keep going. So whatever side won (like say Germany, Italy, and Japan) they turn on each other and keep going and going until only 1 country was left. So take this concept and string it along through GW65 (upgrading tech just like WW1 to WW2), then through GW85, then though GW25 (assuming it want on that long) and then see who would dominate the earth.
