Rather easy to get lost, geographically-wise, but the story is so very, very deep.....It really gets to you, it does. I kind of feel empty somewhat at the end, since I never get to see what exactly happened to the scientists/programmers/colleagues. Even having said that, I definitely feel that this experience was worthwhile, especially the crew logs. The fact that some of them are broken up and all over the place created a mood that I think was perfect for this game... All in all, very well made story. 5/5 here.
