#1 You never really played Nintendo games or
#2 You are deaf
Everybody who considers himself a gamer has atleast one Nintendo Soundtrack he absolutely adores.....
Maybe I just haven't played the right games. So yeah, 1st option.
Even if I had, it might have been a game I played over 5 years ago, where I probably wouldn't have appreciated the soundtrack as much and would barely be able to remember it.
How could I forget Pokemon X/Y, its soundtrack has been amazing so far. I really need to start playing it again.
