Whoa, lots of underrepresented games. Well, they're represented now.
Kaikuluotain (Batman) has nice drive. >:3 I feel a little Rockman in there too, somewhere. *-) 1:45 is great.
Taken (DK). Oh that cowardly ape. c: My favourite section is the xylophone at 2:17.
Whip This Beat (Castlevania II). It really does feel like stage music. Except for that adorable robot. Or maybe because of it. XD
Duel in the Desert (Yu-Gi-Oh). Good use of tension at the start. Perfect desert theme. That woodwind at 1:03! <3
Super Sand Legend (Dragon Ball Z). Reminds me of SFA: Fossil Oasis. >:3
Dreamboy (Smurfs' Nightmare). They made a game about giving smurfs nightmares? o_O Wow, that is messed! The whistle from 2:42 could be from Phendrana Drifts. Nice.
Alien Territory (SolarStriker). The sound from 1:07 to 2:00 is terrific! Such neat background sound. :3 The melody from 2:01 to 2:45 is really cool, especially the pick up at 2:24.
Technomagmar (P: Red). Sheeeh, this could from Road Rash: metal edition. >:3 The melodies are great and it changes up a lot.
Gift of the MAGI (FFL II). Invokes the 90s. c: Ooh that synth woodwind is so nice.
... Keen!
