From about 1998 - 2000 I used to play a wonderful web game, Acrophobia
The game went like this:
The game server would present a randomly chosen acronym with a given them (“Sports”, for example). All players in the room would submit a sentence that fit that acronym. After the submissions were in, players would vote on which was the best sentence to fit the acronym.
Man I miss this game. It was so much fun. AFAIK it disappeared early in the 2000s. There’s plenty of replacements, but I can’t find any that have a large and consistent playerbase.
I love, love, love acrophobia. I found a web-based acrophobia (acrowars.com) but it doesn’t have the same punch as the IRC version. IRC acro games tended to be incredibly foul and irreverant: exactly the way they should be.
