In my initial player decision tree, I decide to keep the focus what position the player would be. Instead, of what is happening in the scene, the location or story. The game starts off with a difficult choice, regardless of the choice you make, still have at least one opportunity. If you take an opportunity you still have to face some type of risk and if you did not take the opportunity you are throwin in to conflict, with a chance of dying. Regardless of how you play the game, the player has to go through some hardship to reach the end of the game.
