inorite? Aside from the Battle of Whiterun, I really liked all the Fort Conquests. They didn't have the baggage of need to seem "Bigger than they are". I only wish they lasted a bit longer.
They should have been able to carry on a la Grand Theft Auto: San Andreas - for anyone who hasn't played, you have gang territories and you have to essentially invade enemy turf and defeat waves of rival gangsters until you've claimed the turf. From time to time your own territories will be invaded and you'll have to defend against a siege to retain it.
This would have been soooo damn awesome in Skyrim. It should end (maybe not 100%, but almost) once you finish the civil war quests, but you should be able to keep doing it until then. Perhaps once you've gained a certain amount you can go for Solitude, but it lets you keep on fighting and defending if you wish.
Now I'm salivating...
