The game script doesn't allow a character to wield double weapons, unfortunately. Claws and Slashers attack power have hence been doubled, so a single claw attack does as much damage as two claws from PS4. Same with the Slicers.
I however have a mental barrier against putting FF music in a PS game, it's as if we plain said "PS music is not good enough so we need to compensate with FF music. I know PS4's music score is weak but Laughter is probably one of the top three tracks there...
Nonetheless, I will be looking forward to hearing your take on Laughter though. And yeah, I love Dancing Mad to death. Actually, I'm listening to it right now. ^^ Screaming electric guitars suit Zio so well, and the synthesizers only make it more awesome.
