The beauty of role playing games is in doing things following your heart, instead of simply reading walkthroughs...
My case is an example: I entered Governor's house, and when I saw so many mercenaries around him, I thought: all these guys are, obviously, being paid by the Governor for some questionable reason... Add to that the ammount of violence in the streets, and the bad behavior of the guard at the city gates, I didn't have any doubt when I saw the dialog box with the option to kill the governor, and killed them all.
And, in the end, I still have a feeling that I did the right thing - even thought I will probably finish the game without knowing what is hidden upstairs, behind that gate in Governor's house... Hope I am not ruining my game.
