afaik, the xbox version is the directors cut version. normal version would be the ps2 one.
but dont ask me on the differences. if they're elemental, i'd maybe buy the game again as well *laughs*
according to the wiki:
Originally released for the PlayStation 2 in 2003, a
Director's Cut edition was later released for the Xbox in
2004.
The director's cut added in several updates to the gameplay, such as a
first-person play mode, a survival mode, a new ending, enhanced
graphics, and a greater number of alternate costumes to unlock.
hrm... changing the camera handling back to how it was in the first game would really have sold me.
