Nayrman's laugh when he is cracking up is incredibly ominous, specially in the Final Fantasy 6 and Sonic Adventure playthroughs.
In Part 18 of the RAWS for Arkham Asylum, Ryan used one of Joker's themes from the Animated Series as filler Audio that worked well... maybe a little too well for its own good without their commentary... At least untilAdam Westkills the mood.
Lost Impact's... Impact on Johnny can be VERY unsettling considering up until that point, Johnny wasn't NEARLY as vocal and hate filled as he was at this point of Shadow the Hedgehog.
