I am having my second adult halloween party this year. We have a seperate party for the kids each year. Can anyone suggest some fun games that adults will actually play? Last year there was a bit of a lull in the action during the first hour or two until everyone loosened up a bit. I would like to come up with some games to play during the first couple of hours as everyone is arriving and getting to know each other. Any advice is appreciated.

theres a post around here that i think is called "adult party games" check it out, its about 5 pages long
I'm sure it will get your creative juices flowing
