Wild ARMs - Courage VS. Romancing SaGa: Minstrel Song - Decisive Battle! Saruin - Final Battle with Saruin -
Meh, unsure. Classic match of focused vs. more technically impressive. Will go with the memorable one (though I voted against it a bunch earlier).
Touhou Chireiden ~ Subterranean Animism - Green-Eyed Jealousy VS.
Shadow Hearts: Covenant - Love Moon FlowerSuper Robot Wars Original Generations - Dark Prison VS.
Castlevania: Symphony of the Night - The Tragic PrinceLegend of Dragoon - If You Still Believe VS. White Knight Chronicles - White Knight Chronicles ~The Travelers~
More consistent? Good match, though.
Xenosaga III - godsibb VS.
Wild ARMs 4 - At the End of the Wilderness Ver. DetonatorPromised Pain would have won here, but not Godsibb.
Grandia Xtreme - Battle 4 VS. Hanakisou (PC) - Winter
Castlevania: Curse of Darkness - Garibaldi Temple VS.
Chrono Cross - Dragon GodUmineko no Naku Koro Ni - Happiness of marionette VS. Castlevania: Judgment - Bloody Tears
at Imbroglio losing but Marionette is still cute.
ANIME
.hack//Liminality - Kioku (Liminality Version) VS. Umineko no Naku Koro ni - One Winged Bird
El Cazador de la Bruja - Forest VS. Tsubasa Chronicles - A song of storm and fire
Both of these would beat the above two. Coinflip. That said awesomeness all around.
ARRANGED
Phoenix Wright: Ace Attorney Justice for All - Gyakuten Saiban Orchestra Album ~Gyakuten Meets Orchestra~ - Gyakuten Saiban 2 Court Suite VS.
Super Mario 64 - OCRemix - Super Mario 64 Devastation's DoorwayYeah, both Doorway or Diffuse World easily win here.
