The best game would be - without question - an all time war-simulation. You pick a date, an age of your character, place, and what status you would have. If you pick noble you might be a general, or a part of some elite squad. What about a knight? A member in a spartan army with sparta at it's hight? Working your way from simple peasant to bodyguard of the king, kill the king and try to take the throne for yourself? Sure, do it!

To bad im not dead yet (I mean, god can do anything right?(If he exist that is, what about a sign?))
