It's not fair that Bethesda started you out with a negative view towards one of the only factions that you have to chose from. It pushes so many people to the Stormcloaks.
I really believe there should have been a neutral opening... or made the Stormcloaks do something just as bad.
Just because that one Commander at that stronghold was... a not to nice person... it influences the players judgement with the faction throughout the whole game. That is not right..
The fact you immediatly get the impression that the imperials are the bad guys was the point of the way it was written. You then go on to meet folks like Rolof and Gurder, good, honest, kind hearted folks and you sympathise with them and you hear of the rebellion and it makes you want to stand with honorable people that have endeared themselves to you.
You can chose to do that, that's understandable, but as you travel across Skyrim and you speak with it's people you begin to learn that it's not that clear cut.
Personally i've loved every second of it, i'm 80 odd hours in and i'm still aggonising over the decision of who to side with. Ulfric seems somewhat unbalanced, and i really don't like to think how things could end up for non nord races if Ulfric wins out, but I'd feel like i'd be betraying the folks like Rolof and Gurder, the people that showed me kindness and trust and that truley believe in the rebellion. On the other hand those same folks don't seem to realise that the empire was forced into the accepting the concordance or the war with the elves would have dragged on and many more would have died and the empire could of lost and skyrim would of been next.
Personally i'm holding out till i have more information that could tip me one way or the other but right now i can help the most people by not picking a side
