the GK series was always ahead of it's time in both storyline and character development. some of the puzzles may be a bit difficult for some but there are plenty of walkthroughs out there! combining the best of point and click adventure with an x files type of plot gabriel knight sins of the father is a joy to play i was lucky enough to play the original game 10 plus years ago and was delighted to see the game return thank you GOG now i wonder if they can secure the rights to the sequels.
