Omikron: The Nomad Soul is a PC and Dreamcast game, released in 1999 and 2000 respectively. A PlayStation and PlayStation 2 port were in development but were cancelled.
In a dystopian future all of human activity is dictated by a supercomputer in Omikron. The player character must uncover the government conspiracy by working with a terrorist group and demons.
Why It Was Cancelled
The Dreamcast version was not very well received, achieving only middling review scores.
Seeing that the console port of the game had an average reception and weak sales, the PS1 and PS2 ports were cancelled at around 70% completion.
