The original game is a staple in the series. I have not gotten the opportunity to play this game myself but I have been told the much like 7th guest this game has lots of puzzles in a haunted house that must be dealt with. It is, however a master of horror and a new series. This broke ground on a lot of games and is considered one of the origin games that was used to come up with ones like Resident Evil.
In the end this is a great series but lacks staying power.
