Is the fight between Stormcloaks and Imperials just a side quest or does it get involved in the main quest? What I want to know is if I can play the main story and some side quests and, 60/80 hours later, go and join the Stormcloaks or the Imperials or will that "story" move along even if I don't choose neither. Does the characters don't get involved in the main quest (because Ulfric kinda seems important)?
I'm asking this, because I don't really know who to choose and the little I read about this suggested
Imperials sound like douchebags (and they did try to kill me in the beginning). Stromcloaks sound like racists. I can't choose.
