Just saw this thread today and it made me smile.
I remember, way back when in a different chat room (Forward Motion, FWIW), back in 2001 when this "game" first started during a midnight session between a friend of mine and one of the site admins (now site owner). It still happens there regularly to the point they added a chat room specifically for that purpose. Warring is particularly popular during November's NaNoWriMo.
Ah, memories.
Carry on, mights word warriors! Go ye forth and kick word butt!
