My gaming group still gets together, even though we aren't currently playing HeroQuest. Usually it involves dinner, and some type of game. The last two meetups involved "Betrayal at House on the Hill."
Have you guys seen this game? It's like Warhammer Quest in that the game board expands randomly as you make choices. You and the other players are investigating this House on the Hill. You slowly make your way through the house, investigating as supernatural events slowly occur. As you activate Events and find Items, you can set off Omens. You then make a roll on the special 0-1-2 six sided dice to see if a Haunt occurs. If a Haunt occurs... The game is on.
You look at the Omen that set off the Haunt and the room where it occurred. You then consult a chart and determine who is the Traitor. The Traitor reads a Traitor's guide in another room and the rest of the players read another guide. Then... The game is truly on.
Now the Traitor and the Heroes have to both work toward their own goals to try to win. It's been hair-raising, and anyone who likes HeroQuest and a bit of gothic horror will LOVE this game. I love it, but I don't want to get burned out on it... Two weeks in a row has gotten me to start looking at Vampire: the Masquerade again, and possibly re-reading Vampire: the Requiem. We'll see though.
