The Psychotron (Merit Studios, CD-ROM for PC/Windows, $59.95) Why did the CIA secretly buy a ''psychotronic generator'' from the Russians? What's really behind that plane crash in Virginia? And why is it of interest to President Richard Marx (not the singer sorry, ''Hold On to the Nights'' fans)? You'll be too bored to care after playing this ''interactive movie'' that mixes excruciating supper-club performances with an aggravating interface (make one mistake and you have to suffer through a badly acted video segment all over again). Weirdest of all, Psychotron bogs down midway through in a seemingly endless game of poker against three mafiosi. Save your dimes and play computer solitaire instead. C
