I recently reviewed the Halloween themed murder mystery game called "A Taste of Transylville Terror" featuring Dracula, Bride of Dracula, Dr Jekyll/Mr Hyde, Wicked Witch, Frankenstein, Kruella Le Devil, Gomez & Morticia von Adums. The game was a lot of fun to play and I can see it's potential despite it not being professionally packaged/printed.
So, don't expect any fancy packaging - these games come in a simple mail order box and have absolutely no frills attached. If you're not concerned about the presentation too much and don't mind the home-made look and feel, then by all means go ahead and try these games out! This is a classic example of a game whose popularity has grown purely based on word of mouth! You can order the games from the website Ace Murder Mystery Games.
