Teenage boys who like FPS games can much easier identify with a faceless male in a suit of space-armor than with a female suit of space-armor who shows only her face at the end. Now if Samus would be wearing a bikini throughout the game, I'm 96.8% sure Metroid would sell 10m+. 20m+ if it were in HD.
