Deus Ex Scratched Ending

Deus Ex lead designer Harvey Smith has revealed to CVG that the team was originally going to send players through a moonbase and a pair of space stations during the game's final moments.
"I didn't want to put Area 51 in Deus Ex!", its illustrious lead designer told PC Zone magazine recently. "I didn't find it that interesting. In fact, initially it was a moonbase. You were going to use the rocket to get to the international space-station (which in our fiction was just sagging and falling apart and barely held together), and from there you were going to use a shuttle to get to a luxury space-station which was going to be like the Titanic."

I think the game would have been a hit either way.
