Okay, thanks. I posted both my comment and your reply to the What Should Mongoose Publish Next? - Conan: A book about lost cities and ruins thread.The King said:Thanks for the link but don't you think ruins and catacomb are a bit out of topic for a sourcebook on cities?
However there is such a thread entitled "Conan: A book about lost cities and ruins" in the forum What Should Mongoose Publish Next?
Moreover where is the need for such a software where you have to create your own dungeons. Printed sourcebooks is very useful for those who don't have the time to draw it themself. Moreover I think this software isn't particularly user-friendly (at least the campaign cartographer).
