World of Dungeons and it’s descendents are a really interesting phenomenon. The game started as a kickstarter bonus for the Dungeon World RPG, and is just a handful of pages.
It’s true WoDu itself in particular is so minimalist it’s just barely playable, but then that’s also true of the earliest versions of D&D. I think Breakers, the first WoDu Turbo game, was a real watershed. It’s a much more complete game, ditches the legacy stats and has an up to date and highly functional character sheet design. It even comes with a handful of monster stats. Leading on directly from this is Rovers from Aviatrix Games, a really awesome Traveller mini-clone, complete with starship design system and a world creation system in just a few pages. Rovers completely floored me, next time I feel like running Traveller, or a Firefly or Dark Matter inspired game this is what I’m reaching for. Yes you get less than in any edition of Traveller, but terseness and simplicity are by themselves incredibly valuable attributes.
Another game I can’t pass by without comment is Streets of Marienburg. It seems to bypass Breakers mechanically, but it still one of the most complete WoDu hacks out there, even including a mini setting! Character Generation is appropriately expansive for a Warhammer Fantasy Roleplaying inspired game, and it has a nice mini magic system.
Breakers was still quite minimalist, but focused on a specific premise that made it feel much more complete than WoDu. Rovers and Marienburg though both bring a lot more to the table, fleshing out the game with extra options and mechanics that add flavour, and focus on a specific setting or activity but still in a super stripped-down way.
My one caveat about all of all these games is that you really need to already know how to play an RPG to really make them sing. That’s absolutely true of WoDu itself. As a kickstarter stretch goal for Dungeon World it was aimed squarely at people who already knew how to not just play RPGs, but PbtA games specifically. Breakers, Rovers and Marienburg take a little more space and effort to provide a more complete package. Still though, they rely on a lot of existing knowledge and experience in the reader. That’s not a bad thing though, why repeat a lot of ‘boiler plate’ introduction to roleplaying stuff unnecessarily? It just means they're not great as introductory games by themselves.
One niche these games fit particularly well is that they are pretty easily adaptable for a new setting. If you want to adapt WoDu or Marienburg to a new fantasy genre it's pretty simple to do. Similarly Rovers is fairly easily adapted to your favourite SF setting. This is a lot more work for the heavyweight, 'complete' PbtA game systems.
