Everything: Too many games evolve around the main character. My idea takes a different aproach:
You are an annonymous assasin (ninja?) that is hired by one clan to terminate an important individual in another clan. Your mission is to get in the premesis of the other clan and terminate the person. During your inflitration you learn that the target is a pregnant female and that the birth would give that faction an advantage over your employe. Eventually, you are left to decide if you will go through it or take a different approach resulting in different endings. All troughout you identity will remain annonymous.
This game idea can easy be tailored for different settings/time eras/game mechanics.
