A recent release that may have flown under your radar is Soul Sacrifice, an action RPG for the PS Vita. One of the main combat mechanics is the decision between sacrificing or saving downed enemies and allies. Saving an ally brings them back at the cost your health, while sacrificing them grants you an extra special attack. Sacrificing enemies restores charges for casting magic, while saving them restores a portion of your own health. Players even have the option of sacrificing parts of their own body. While this idea makes combat interesting, it would be nice to see the choices you make at the end of each level have an effect on the story and the outcome of the game. Essentially, does your choice really influence the direction the game takes? Many games have toyed with the idea of influencing the world around you, as well as the citizens who reside in it. But which games did it well, and which failed to influence the player to continue playing?
