The Civil War questline in The Elder Scrolls V Skyrim makes it look like the player can have a significant effect on how the game world turns out. Skyrim seceding from the Empire or Skyrim staying in the Empire or the neutral divided Skyrim. Clearly, Bethesda will not be able to satisfy all three as to a canon outcome. Further, we have seen on these forums how the in-game Civil War turns into forum Civil Wars ("life imitating art" ).
Should Bethesda continue to make questlines where the player can choose any side, including neutrality, in a conflict even though there can be only one canon ending for any given in-game questline conflict?
