Hello, so i made this list with all exclusive games/content for original xbox.
Types of exclusivity:
Full - there was no re-releases of this game.
Console - there is PC version of this game.
Content - there is bonus content available only for Original Xbox version.
6th generation - there is version for next generation consoles or re-release, but no versions for other 6th generation consoles.
