Some nice choices bro

but but but...

#1 and #17 are the same thing

 Thanks for catching this. Replaced it with something really great. Not a huge fan of the game, but soundtrack is still badass.

Well, never forget is so good that it deserves to be on the list twice.

          Yeah.  I love it so much.  Dire Dire Docks came so close, but Never Forget simply deserves the gold medal.

Some real nice picks in there. Especially the Resident Evil 3: Nemesis ending music, not many people know about that one, it fit the mood of the ending perfectly. The entire OST for that game is overlooked in my opinion.

             RE3 had a really good soundtrack. RE soundtracks in general don't get a lot of attention.

This is still one of my favourites, so much tension.

Nice picks for the Sonic games too.
