I have been playing Skyrim for a while, but have held off making my decision as to which group to join.
Imperials - Looking to control the Stormcloak rebels and maintain control
Stormcloaks - Nords looking to overthrow the oppressors, and some "terrorist" activity. Responsible for the dragon's coming back?
How did you make your choice?
What storyline might I have missed leading up to the decision (not really interested in results of decision)?
