Imperials are better, they are trying to set up a government while the stormcloaks are starting a war they can't win
Yes Stormcloaks are racist towards everyone who is not from Skyrim.
Kill a Stormcloak officer.
yes u just have to do quests for the empire like you did for the stoarmcloaks and also help the empire take cities and bases
If you support the Stormcloaks for the Civil War quest, then yes, Jarl Ulfric will become High King of Skyrim. If you join the Imperial Legion, he is killed.
No, I have finished Theives Guild and Dark Brotherhood and nothing's happened to either of the factions.
Factions you can join: Companions College of Winterhold Dark Brotherhood Stormcloaks Imperials With the Dawnguard DLC: Volkihar Vampires Dawnguard
You can start the Jagged Crown quest, and take the crown to the leader of the opposing faction. So instead of returning the crown to Ulfric, take it to General Tullius instead. However once you complete that quest, that's the point of no return.
Bards College-The Blades-The College of Winterhold-The Companions-The circle-The Coven of Namira-Dark Brotherhood-Imperial Legion-Nightingales-Stormcloaks-The Thieves Guild
If you mean the high king, yes I believe that you can side with the stormcloaks and then you kill the leader of the imperials and Ulfric is like oh I don't want to be high king, so in effect you can become high king.
Even if you joined the Imperials, you can switch sides by doing the Jagged Crown quest, delivering the crown to the Stormcloaks. However if you've already completed it in favour of the Imperials, then there's no way to switch sides.
There is no way to finish skyrim. There is always something to do. The dark brotherhood will have a quest or the companions or the thieves guild. and although it may not seem heroic, you are a hero. But you must be hated to save skyrim. You're the hero skyrim deserves, but not the one it needs right now.
I assume u mean the battle for whiterun u cant stop it if you join sides but if u dont join impearials or stormcloaks it will just stay the same and u wont have to fight and the main story line will be differnt.
