This game is an absolute Classic. It absolutely does not deserve the gamespot rating.
The puzzles and story were what made this game worth playing. It might be considered a bit out there. The main plot is that a giant asteroid takes a crew from a space ship light years away and strands them on some unknown world inhabited by "ghosts" of aliens. It takes some interesting twists and is very serious but retains its sense of humor. "What would have happened if I hadn't packed this shovel...no that's not worth thinking about (or the rough equivalent of that line)." I managed to figure out every puzzle in this game on my own eventually except for one... dead alien turtle bones is a fairly difficult, but oddly straightforward puzzle (how many games have you played where you have to put all the bones of a turtle back together in order to reanimate it correctly, while adding an important twist?)
The voice acting was extremely well done and this was done at a time BEFORE many games used this. I also remember going "Ooooh, it differentiates between the right and left speak!" This was the first game I had EVER seen that in.
So yes, play this game. It is worth your time. I love it every bit as much as I love Indian Jones and the Fate of Atlantis.
