Worst Adventure Ever!
Okay, I'll admit, there are definitely worse non-commercial games out there, and there are a few things to recommend this. It's got some funny/clever bits, the graphics and music are okay, the sound is pretty good unless you're tight on memory.
But that's where it ends. The actual gameplay is Bad with a capital SUCKS.
First off, there hardly is any game: All three variations can be finished with thorough exploration in about an hour apiece, and the two human characters' plotlines are virtually indistinguishable aside from gender. As the game comes on approximately 8 billion 3.5" disks, it takes longer to install the stupid thing than it does to play it. Because of the simplistic interface, there's barely any hidden stuff to discover. Once you've played all three characters, you've seen everything there is to see. Considering this was a $44.95 game at the time of it's release (and still goes for that much now due to its collector's value), you will feel SO gypped.
Second, while the early parts are interactive, a lot of the game consists of waiting. You wait for people to finish talking, you wait while travelling through space (twice), you wait for game events to happen. Were it not for all of this waiting, the entire game would take about 30 minutes to play through. And these are not like the "cut-scenes" in many games these days: There is very little animation, nothing to interact with to pass the time, and it's duller than the most boring visit to great-grandma's house.
Third, it locks up. A lot. Especially if you're playing with the voices and have less than 600K of base memory. Meaning you have to restart and go through the waiting parts AGAIN.
The Bottom Line
Activision apparently released this game only to try to recoup some of their losses from developing it. It's too short to be worth the exorbitant price you'll spend acquiring it, and not entertaining enough to keep you from feeling royally ripped off. This game should be Avoided with a capital DON'T WASTE YOUR TIME.
