Hmm. The Dragonborn will need an army. Fortunately, I can think of a group, large in numbers, that already has one hold soiling their trousers at the thought of them.
What I'm saying is, how about recruiting the Forsworn? Put right what was done to them by both the Empire and the Stormcloaks... or betray them yet again, your call.
The Forsworn don't care about anything beyond the Reach, unfortunately.
I am planning to try and include multiple Jarl options for each town- in the interest of quest compatibility, you can pick the Imperial Jarl or Stormcloak Jarl (so, for example, you can keep Balgruuf in his position), a third option for some towns (an example of this would be allying with the Forsworn and putting Madanach or some other person in charge, thus making the Forsworn 'friendly' with your faction but really, REALLY angering the Nords across Skyrim, and hitting the player with pretty substantial penalties everywhere else). The 'third options' will have very tangible effects upon the game- if the player wants to place a crusader in charge of Riften to clean up the blatant corruption there, increasing tax income from the city, he will have to meet it with assassination attempts and such from the powers that be.
Then, last, there's the Fourth Option, which is placing one of your Followers in charge of the city. For example, placing Kharjo as Jarl of Windhelm.
I've also been doing some in-game experimenting with script commands, and I can say, quite pleased, that the script language is MUCH more powerful than anything Oblivion offered for this mod. The original Oblivion plan would allow the player to completely customize his army down to the races of troops- the player could, for example, make his armies Legionaries and Auxiliaries, with only Imperials being Legionaries but allowing a mix of other races to be Auxiliaries. Now, the problem with Oblivion was that in order to gain the proper variety, I would have to hand-place exact duplicates of a soldier at each place, except a different race for each one. No more! SetRace appears to work- somewhat- hopefully it works better in the CK. But that should decrease the workload substantially.
Naturally, everything is on pause until the CK itself comes out, which should be fairly soon. But I am eager and anxious to get to work.
