I wanted to try my hand at something, and here is my current draft, just before the holydays... So that perhaps you might give it a try and send me some feedback, if you happen to play HeroQuest in these days of festivities.
What is it? It's a series of instructions and tables to generate a random map in HeroQuest.
It uses only the original board and the original materials (no additional monsters, no special furnitures, just normal dice, etc.). It also provides you with a mission or theme for your dungeon, so that heroes know why they're going in there (except for killing monsters and taking treasures) and who or what they're looking for.
It has some variety: so it can generate a dungeon only of green monsters, or just undead, or a standard mix, it can give life to multiple-levels dungeons, and has guidelines for basically everything, including hidden traps, secret doors, wandering monsters. There are also some simple rules for a few special rooms, to spice up things a little bit.
Of course it would run better as a program on your phone or on a website, but this is if you want to play totally off the grid - just print it up, and play forever!
(Feedback totally welcome! I tested it a few times but without playing, but I wanted to put a draft out for christmas when maybe you all have more time to play and give it a try!)
