Pokemon Dungeon Crawler is a glorious low-fi homage to both Pokemon and old-school dungeon crawlers.
It's 62 pages, with classic art from Red & Blue and a layout style that's reminiscent of old Game Boy text.
Content-wise, PDC feels very faithful to the playful, curious spirit of Red & Blue, but it's also got lore elements similar to Mystery Dungeon. I'm a casual fan, but I think fans who are deeper into the material will also have a great time here.
Mechanics-wise, PDC is D20, and I think the D20 engine really works for the cozy, crunchy, retro thing it has going. I also think it's one of the best, if not *the* best, adaptation of Pokemon to a gaming engine that I've seen (the other candidate being Pokethulhu.) Pokemon is hard to adapt, and it tends to either get bloated with complexity or simplified until it loses its flavor, but PDC deftly threads the needle between those two outcomes.
PDC also adapts things in ways I wouldn't have anticipated. For example, evolutions for all pokemon are now stone-based, and confer an additional Move. Moves use PP, which I would've liked to see tied to Class, but which everyone has a default pool of. Instead of using Moves, you can also just regular attack with equipment, so Moves are closer to spell slots rather than a depletable survival horror resource.
The PDF is quite full of content, and it includes TM/HMs, setting hints, a full adventure, a bestiary, equipment, and a some advice both for GMing and for GMing this game specifically. It's not 100% comprehensive, but it is absolutely enough material to play with, and there's a clear road map for how to add your own content if you want to.
Overall, this is a treasure, and it's free. So given the, ah, parent corporation's American branch's history with well-intentioned fan projects, I'd suggest snapping it up while you can. And also writing fan material if that's allowed. Maybe there's a herd defense we can do to protect this thing.
