This game has not lost it's fun. It is a timeless classic and forever on the playlist of LAN parties. If someone says they do not like this game, they are very likely quake 3 players :D
When I first played this game I was about 8 years old and living in rural Finnish countryside. I didn't understand much English and my mother had to translate for me as much as she could, and do remember that this was well before Internet and help of google translate like services. Trying to figure out what is "Hypo dy-toxin" and such techno babble by using only English travelers dictionary must have been frustrating... sry mom :) Though the game was beyond me as a child, I still always remembered this game to be fascinating. Later as an adult I rediscovered this gem of a game while I went through my old Dos game library. When I played it through the first time (understanding English language really helped). I was very surprised how well this game was made, puzzles make sense and you have more than one way to end a mission. Though the midi music is average but voice acting is absolutely top notch. The graphics which were beautiful at the time still hold out to this day. You never feel as 'alone' in this game since you have Mr. Spock and Dr. mcCoy to keep you company, their dialogue being fun and true to the characters, the best thing is that you feel you are not just dragging them along, but they actually contribute to the mission by giving advice and their view of challenges you face. The usual puzzle game approach of "use every item on everything" might not work here, since having more than one solution to some of the puzzles will affect the ending result of the mission and your score. This is what makes it so interesting and even gives the game replay value. But it's not only your score that you should worry about. For you can die in this game, so do think twice before you start waving a phaser around. So I strongly recommend to buy this game. Only bad thing I can think of the game, is that this being my first experience with point&click genre, all other games after it feel very linear. Good luck captain, and do try to bring the red shirt back alive.
