Hey, Brad, you should get the Troop to become a kingdom, if you roleplay, that would rock! You could have the Troopa Kingdom (no copyright infringements) with flying airships to raid other kingdoms.
Speaking of which, every kingdom should have a certain "weapon" or something special that they and only they can use each. Maybe one kingdom will have a flying ship, another one would have a better location for a Kingdom? Also, Kingdoms should have 2 or 3 towns within them at least...
