The great thing about Flashback are it's tilesets, not the animations, so much. Sure, they're smooth a a recently dead teenage girl's bottom, but they're rotoscope-based, which is CHEATING LOL but the tilesets... the tilesets!!
Flashback comes back from a time ( like the bitmap brothers games) when Art Direction was existing in computer games, and besides trying to mirror reality, studios went 'how can he make this distinctive and stylish?'
