Basically list your top 3 video game stories from each gaming generation. You only need to go back as far as you desire and the only stipulation is time frame. If you're going back to the 90s, start in 90-94, then 95-99, then 2000-04 and so forth. Just try to keep it within an adequate time frame that is not too short or too long. I'm doing a bit of research into a pet theory of mine.

Obviously you are not limited by genre or gaming device so have fun.
