I don't always promote things like this but for this Bundle of Holding it is Dungeon World!
I don't talk much about my love for Dungeon World in my blog. I probably should though. Dungeon World is probably my favorite gaming system. I know...I know...I write One-Page Adventures for Swords & Wizardry (OSR Systems). But Dungeon World caters to my GM style more than any other game. And I often take that style of GMing to my Swords & Wizardry games. I will probably record a podcast episode of what my style of GMing is.
Anyways, I highly recommend this Bundle of Holding: Dungeon World
Experience a game system that I love!
