Fangsatz
Word guessing game similar to Catch Phrase designed for online play
Make sure UDP port 1110 is open on the host machine, and have any number of remote people join and guess at words in turns by giving clues over a separate voice chat service such as Skype. The game was intended to be played with rules similar to those of Catch Phrase, but is designed for remote play for groups that can't get together in one place.
