Official level/map editors
I am sure many of you heard and know that in most games the levels you play were built using some internal level and map editors. "Reverse engineering" made by people like CFOU! or JOTD and information which can be obtained after completion of the game (eg. Battle Isle, History Line) or from the interview with the authors (Traps'n'Treasures) are an evidence of that. Does anyone have such level or map editors? I know that there are some unofficial tools which help you to create extra levels and maps (eg. Battle Isle map editor, History Line map editor, Benefactor map editor) to many games but maybe someone has an access to original ones.
The only offical one which I know is the map editor for Hired Guns. Scott Johnston released him some years ago.
