I just had my murder mystery event rejected for the Game System field being specified as "homebrew" which is what I submitted it with the past 2 years.  It is a custom written murder mystery story, not a boxed/store bought game.  Any idea what I should list this as?  It would be helpful if this were a pull-down list if specific values were required.

Since I cannot find a way to delete the post I want to update to advise that this was an error on the part of the reviewer and GenConreached out to notify me that it has been corrected.  Homebrew was the appropriate Game System.
