Firstly, sorry for replying so late. My internet has been horrid over the past few days.
Second, the main idea I have is that the player will be thrown in the middle of a war between two factions, which the player will then effect with his or her actions. They'll meet various other characters along the way, all of varying backgrounds, personality, and relevance, and all of which I intend to be able to die at some point or another in the story, once again based on the players actions.
