acronym:face to face. A game which is played by having all players physically present in the same location for the duration of the game. Many strategy games can be played either FTF, PBM (play by mail), or PBEM (play by e-mail). Diplomacy is a game that frequently has this distinction; only games which can be easily played in either format will be referred to as FTF (whoever heard anyone say, "I'm playing FTF Candyland!"?).*
Not often will you find an English sentence terminated by so many different punctuation marks.
