The game engine is called V-Cruise and it was previously used in Reah.
The FAQ at Dreamcatcher's web site provides this interesting note about the name of this game:
"After reading tons of customer letters urging us to change the name of the difficult to pronounce Schizm and also speaking with thousands of customers on the phone who mispronounced the title Schizm - pronounced SKI-ZIM, we have decided to market the title under the name Mysterious Journey, subtitled Schizm."
Of course I guess making a game with a difficult to pronounce name came naturally to Maciej, Zbigniew, Lukasz, and the other designers at Detalion.
On Nov. 26, 2001, Schizm was awarded the Adrenaline Vault Seal of Excellence Award.
