Sorry to be so slow in responding 8dog, but I've been ill and have not been on line. This is a copy/paste of my comments on that series of games. Remember, this is just one person's impression:
Haunted Hotel: Charles Ward = Darned good, excellent puzzles, complex, long. Replay.
Haunted H.: Phoenix = Played Demo: Not that compelling, didn't buy.
Haunted H.: Axiom Butcher = Played Demo: Didn't bite.
Haunted H.: Personal Nightmare = Played Demo: Decided against it. Tired of the haunted theme.
