I found this program to be very useful for making adjustable, random maps. There are a ton of options on this program, it is 'user friendly' and I was quickly able to put it to work for me. I will be using it almost exclusively for my published RPGs.
The categories on the program are adjusted by percentages. They are too numerous to list but include rooms, room sizes, doors, secret doors, colors, shadows, traps, corridors, size of corridors, style of corridors, stairs, layout style and the list goes on and on.
It is designed to print out directly but I wanted to use it to make maps to include in my published adventures. I had a question about this and the designer told me how to save them as PDFs. The support for this is excellent.
The price is a big plus. I highly recommend this program for your dungeon mapping needs. Black Death Publishing is well satisfied with it!
