EDIT: On second thought, they are .xnb, not .wav. I guess redigit changed it, was pretty sure it used to be .wav
Reminds me of a friend who was surprised that I had all the Warriors games' openings (PC version) in a single folder. "Where did you download them from?" "F:\Games." The Dynasty Warriors games would probably take a fourth of the space they do on disk if Koei bothered compressing their video files.
