Almost every game-related wiki contains trivia about their games. So why not collecting funfacts about the Project DIVA universe? That's why I'm starting this new subpage on the wiki: http://projectdiva.wikispaces.com/Trivia+%26+Facts The page is under construction. Feel free to submit funfacts etc. in this thread!
Oh, wow! Thanks for including my Meltdown find! And maybe too add to the page, you could include the outfit references in F, like BB Operator being based off of Border Break Union or Rin's Egg Mage outfit (I don't remember where that one's from though).
I just found this one out but while playing the song ACUTE (most notably on Extreme), I noticed that whatever note you're pressing the most symbolizes who's singing. X's (blue) when KAITO's singing, Triangles (green) when Miku's singing, and Squares (pink) when Luka's singing and in the end you press all three. This is why there's rarely any circles in the song (they're mainly in the instrumental part near the end). If you watch a video of the notes or play the song yourself, you'd see what I mean.
