I'm the youngest of my siblings and I have 3 older brothers. They all loved playing Megaman so it's always been a part of my life. I remember I started singing Flashman's theme while my brothers were playing MM2, and they just looked at me and stared. I felt terribly awkward.
As for my first game, I played Megaman a couple of years ago. Decided to try to go through all of them in order, just Classic and X series for now. Being the youngest meant that I didn't really get to play games, just watch, so I'm kind of a late bloomer.
