From the E3 2003 demo of Geist, it can be concluded that many areas have been redone and placed in a different order. The story also appears to be a bit different. For instance, Bryson is not dying, but simply locked up when you meet him. In an early screenshot we can see a monster that isn't in the released game. As for gameplay, much more has changed. In the demo, Raimi does not have the violet tinge to his vision when he is not possessing anything, nor does the physical world gets slower. Dispossessed hosts in the demo are unconscious, while in the game they are still awake. In the game, Raimi looks roughly like an ethereal version of his physical appearance, but in the E3 demo, he's a far more traditional ghost with a skeletal appearance and no legs. Also, in the game, Raimi does not fight other ghosts until the final levels, while they appear to be common enemies in the demo. Two abilities ghost-Raimi possesses in the demo were heavily adjusted. In the demo, Raimi can shoot ethereal blasts in this realm, while he can only do that in the ethereal realm in the game. The ability to influence objects from a distance through psychokinesis was removed and replaced with the ability to influence objects through possession. [Info from Wikipedia]
