I'm an indie game publisher who has been having success with my critical hit dice compatible with all systems.
I'm making these books of adventures to cover a DM's ass when they run out of prepared material or the players go off the rails and their improv juices are running low.
Each adventure is formatted so you don't need any prep. You can grab a book in the middle of a session, flip to a fitting two page adventure and seamlessly start running it after reading only the first few sentences.
Here's a PDF of a full adventure from the Roads & Ruins book, so you can see what I mean: https://deckanddicegames.com/wp-content/uploads/QuarterShots/QS-Roads_DecoyEscort.pdf
Feel free to print this out and keep it for the next time players go to leave town and you don't have anything planned for their trip.
They are super light on mechanics, so they work with Black Hack and any other fantasy role-playing game. For instance, it might say "Observant PCs notice..." which the GM can translate into whatever perception-like mechanics are appropriate in their game.
If you like it, please check out my Kickstarter with several books full of these adventures: https://www.kickstarter.com/projects/deckanddice/quartershots/
