If this game had been released a little earlier in the United States it most likely would have faired better, but by the year 2000 the 3D graphics were quite dated.
That said, this game was one of my most memorable gaming experiences, right up there with the first time I played Zork, Myst, and Half Life.
The puzzles are mostly logic based, and while some require inventory items that can be a little non-logical to come by, it didn't takeaway from the experience, but rather enhanced it for the most part.
