There isn't an "Xbox X" version, so the game runs exactly the same on all Xbox consoles. Graphically, there is no difference either. Audibly, like all Paradox games, it is 2 channel stereo no matter what you set your console to or your receiver to (you can use Dolby PL1, but that isn't true Surround Sound like PL2, DD, or uncompressed PCM 5/7).
