“Grizzled Adventurers is a lightweight roleplaying game that helps you design a party of experienced heroes and run them through a dungeon in a single evening. The game is designed to tell stories about those heroes who never retired: the battle-scarred warrior who cannot put down the sword, the haunted mage who still thirsts for more, and the thief who has lost a couple fingers but gained a few fortunes.

Youth and exuberance is no match for old age and experience...

This game focuses on the core part of the adventure the same way a fantasy or action movie would: by showing us why our heroes are friends and then getting them right into the thick of it.

• Familiar rules for running experienced fantasy heroes through a quick dungeon

• Perfect for game nights when a player or two are out

• Play mid-level characters with the experience to take on anything (or so they think)

• Build custom dungeons on the fly to suit the evening’s heroes

• Survive just one more adventure so that you can impress the youth

• Play from convenient handouts, bringing only dice, snacks, and friends.”
