A fun game that my family enjoys (mine are all older ones too) is something we found last Christmas.  It's called WOLF I believe, but there are many versions.  It's a deck of cards that get passed around by a leader.  Your card describes who you are in the community id:  good guy/bad guy.  There are all kinds of townspeople and the evil one/ones are trying to kill off the good ones. The leader sets the scene and you all close your eyes.  The leader asks the bad ones to open their eyes, then the good, then the others, one by one.  He alone knows who is who.  You ask each other questions and you evade questions or answer depending on your "card" idenity.  All of my group (many are theatre trained and debate oriented) adored this game and continue to play it at their own parties.
