since 1986, multiple military groups for 26 years, and three separate campaigns since I retired.There is a slight difference between the title of this thread (and poll question below) and the actual statement you are saying is true or false for you (it was too long for a title), so read carefully below:
True or False: "As DM I have created (or created collectively with others) a homebrew D&D setting which I have used for two or more separate campaigns."
"Separate campaigns" means two or more distinct series of games that do not share characters or is not a direct continuation of past games. They may or may not share players.
