Free GM Resource: Tunnels and Trolls Random Dungeon Generator
This Tunnels and Trolls Random Dungeon Generator seems rather simple on the surface and it makes a rather straight-forward procedurally-generated adventure, but it is a HUGE adventure.
I did what I thought would be a quick cut & paste of the generated web page adventure into Microsoft Word and it was 31,000 words long on 93 pages!
That was the default setting of 4 levels for a group of 4 1st level adventurers.
Now I don't play Tunnels and Trolls, but with something like this, which is geared for 4th, 5th, and 7th edition use......I might give it a go. A lot of work went into this for certain.
