Scrabble. Seems to be a general favorite around here. Maybe because us typology nerds are so obsessed with arranging and rearranging the letters I, E, N, S, T, F, P and J. It's a small step from doing this for fun to using the whole alphabet for winning points.

Chess is good. Haven't played it for a while though. I love Reversi too, but only play it on the computer, and haven't played it for a while either.
Scrabble is good too. Monopoly. Cluedo, hehe.
Freude, schöner Götterfunken Tochter aus Elysium, Wir betreten feuertrunken, Himmlische, dein Heiligtum! Deine Zauber binden wieder Was die Mode streng geteilt; Alle Menschen werden Brüder, Wo dein sanfter Flügel weilt.
