As in the title, it is required to play the game, each time you have to find a matching fingerprint in order to play the game. The game says the fingerprints are in the documentation, well they are not attached. I had to find them on the web and have to match each time I launch the game. Due to poor quality I fail more then I wished. Dear GOG, is this really necessary? Ruins whole game experience and wastes a lot of time.
This game was coming and going off my radar for the past 25 years or so. It always appealing and mysterious, 6 disc Amiga version felt like it must be something marvelous, most games adventure at that time could be contained on 4 discs. But it never happened, non of my friends had it, it was not popular. And now, already in my 40's I found it and finished it (with a help of 3 different walkthroughts), my first Sierra adventure game. It was worth waiting for, the experience was exquisite, I feel like 15 years old kid again. The experience is priceless. The amount of research and writing invested in this game was ahead of its times, I can only hope that value of this game is high not only for those born in 70's but also for younger audience.
