They were sued for the main song of MGS3...it was one of MGS2's major songs as well.
The song that claimed it was stolen from sounded nothing like it other then two tones.
But because of that small mishap they took out one of the series greatest songs.

Well I must admit, it does sound very similar.
It's a shame that it had to be taken out of MGS4 because that was the main theme for the previous games, whoever sued obviously wasn't a Metal Gear fan.

"Way To Fall" is a great song, I think it went perfect with the ending of MGS3. I was surprised to find out that it was a Starsailor song, I didn't think they were big in Japan.



*dies* The Metal Gear series has been one of my faves ever! (along with the FF ones, of course!) I'm definitively gonna join this FC!!! *loves Hideo Kojima for creating the MG saga!*
