Betrayal At House On The Hill-A Fun Though Sometimes Confusing Venture

First off I need to say that I'm a moderate gamer. I dabbled in Magic: The Gathering in junior high and never really cared for it. Aside from a couple half-handed games of Dungeon and Dragons I pretty much gave up on the entire thing and never really delved into the world of gaming (especially when Pokemon bombarded it).
Now I'm more into gaming-card games, board games, rpg's. One game I got for Christmas, Betrayal at House On The Hill, is one I've found myself trying to master, but to ill effect.
The premise is that you and your co-players are a group of people on a trip into the "spooky" house which lies on a hill on the outskirts of town. You start by exploring the house. As you move you add new rooms to all three stories (basement, ground floor, and attic). Each room brings new challenges, rewards or surprises. Eventually, through a chance turn of events it turns out that one of your party, maybe even you, is a traitor who's led these people here under false and malign pretenses. No one knows who the traitor is, not even the traitor, until the 'Haunt' is revealed.
The Haunt is the chance roll that starts the supernatural event in the game. For example you can all be haplessly walking around the house and then when the haunt is revealed, it turns out that the House itself is alive and you've dragged the others here to let the House feed on their energy and they have to perform a special function to get ot alive. Or it turns out after the Haunt is revealed that a player is a cult leader who has stranded the others in the House to sacrifice them and bring his other-dimensional God to this plane.
This game is definitely fun. It takes some intuitive guessing and some strategizing as far as room placement, card usage and companionship. The game is always different, scenarios change with the smallest detail (what room the Haunt was revealed in, what item revealed the Haunt).
The main problem I have with this game is that for the three times I've played it I've always been the traitor! And it's difficult to tell who's won after the game is over. Many of the scenarios don't really allow you to distinguish, when a game is finished, who the victor is. So alot of the time you're left guessing. Although it's vague in some spots and takes a couple of games to really get the rules and mannerisms down, I recommend Betrayal at House on the Hill. It's solid fun with a quirky supernatural twist that Stephen King, Robert Bloch or even H.P. Lovecraft would enjoy.
