Twilight 2000: Airlords of the Ozarks
Twilight 2000 had the problem of reaching a good stopping point (escaping Europe) but then being commercially successful enough to continue. Airlords of the Ozarks is a very blatant example of how the style shifted, to the point where I once used the phrase “Arkansas vs. the Blimps” to describe other settings doing the same.
I feel now that GDW might have written itself into a corner and for better or worse had to change tack instead of copy-pasting classic adventures only in different continents. But to go from brutal survival to almost Jon Land/Mack Maloney level conflicts against airships with nuclear missiles? It may have been too far in the opposite direction. But I don’t fault them for trying.
Plus Airlords is still vastly, vastly better than the abomination that is Kidnapped!
