Betrayal at the House on the Hill is a pretty social and friendly game. It gives the illusion of making choices, but usually the right one is pretty obvious, and everything after that is pretty random, so anyone can win. It's rare (though possible) for someone to die and sit around waiting for half an hour.
Much of that makes it frustrating for extreme gamerz, but for people who aren't invested in complicated rule sets and deep strategies, it's perfect.
