Trivial Pursuit is definitely the top of my list...I have way too many useless factoids floating around in my brain 
Also:
Life
Scrabble
Monopoly (but not that often)
Boggle (does that count?)
Sorry
Backgammon
Couple of D&D board games that I liked playing with friends: HeroQuest and Talisman
Interesting too that nobody has mentioned the game Aggravation. That was a family tradition whenever I went to visit my grandparents...and I don't think I've played it since they died.
