Only very small differences, but as I can currently remember in posting this, the PS3 version has:
- Weaker effects (water, electricity, etc.)
- Tougher control due to ergonomically inferior default controller on Sony's behalf
- Hidden mini story in the credits, which lasts about 2 minutes :sadface:
- Insanely eery and disturbing background music for the 'Disorder' brings about fear and creates a different, more immersive atmosphere. If you've ever played Metroid Prime 2, think Dark Aether. That scary.
- Minute programming differences, such an example being a 'double jump' execution from transforming back into sprite form. Other examples clearly forgotten.
- No options. Evident in almost all PC/Console-shared (multi-platform) games and one of the most agitating things ever to do to a player. Seriously.
- Cloud storage for save data (So you can download your save data onto another PS3, so long as you are using your PSN account, and have the game itself on that different console).
