This is my favorite video game.  I still remember seeing the preview for it on TV: "An evil empire is sucking the life force from the planet, destroying all that's in its path.  It's up to one soldier of fortune to save the world.  If he succeeds, you survive.  If he fails, you can always hit the reset button."  After the game came out, it was months before I could afford it.  It was worth it.  Over a decade later, no game has come close in meaning as much to me as this one.
