The only winning move is to not "play". Let them fight their silly war without you.
slightly off topic rant here.
This is the worst attitude a person can have. Video game or not, doing nothing to lend your aid to a situation is just as bad as joining the Thalmor. You are part of the Empire and become a part of Skyrim when you decide to take the Mantle of Dragonborn and are accepted by its people. Are people after the war in game debasing you? Is the side you won for treating you beneath them? Or are they raising your status in the Empire/Stormcloaks and gifting you with honorable weaponry and welcoming you into their ranks further?
Are the citizens who supported your side calling you a lackey? Or did you protect the lives of countless others. By doing nothing, and this is in the perspective of the game's world, after becoming Dragonborn you could save MANY lives on both sides by helping end the war quickly and efficently.
I'm sorry but I don't care what side a person takes in the game, and I am well aware that it's just a game. However I cannot stand when someone thinks doing nothing is the "Best" route for them. By doing nothing, you help prolong the war and end lives. Everything has a consequence. People should do well to remember that.
(Also I'm sorry if this seems like a direct insult, it's not intended to be. I'm speaking in general.)
Rant's over. Sorry, just get tired of seeing the "lolnotmyproblem" attitude that plagues humanity irl.
