The Hex Hack is a series of system-neutral tables to support a campaign rather than hexcrawl rules or a hexcrawl key. While being system neutral, it probably works best with games like B/X, Old School Essentials and Swords & Wizardry. To clarify from the Description, the 350 unique entries are 350 results on the different tables. The table entries are short and colorful, a step up from the usual bland entries of many random tables sold on DriveThruRPG. You need to do quite a bit of work to bring the people, places, things, and premises to life but I think The Hex Hack is worth the price. It could supplement a hexcrawl campaign nicely.

Not rules to run a sandbox hexcrawl with The Black Hack, like I was hoping for. Instead, it's a very nice homage to a classic sandbox the author remembers fondly. Seems like the kind of thing where you could sit down with some players who have no idea what they're doing or where to go, and just start rolling on tables. It's very focused on the "enchanted forest" style setting. If you'd like to start rolling with this theme, go for it! If you're looking for more structure to lend to a Black Hack game you're already planning, this might not be for you. Lots of heart went into this production, it shows.
