from the itch.io description: GROK?! is an adventure role-playing game where you assume the role of an adventurer in a gonzo world of boundless plausibility and use your ingenuity and resourcefulness to overcome strange and perilous threats. Inspired by the core tenants of old-school adventure games, GROK?! was influenced by greater works such as Cortex Prime, Electric Bastionland, Fate Core, Freeform Universal, Index Card RPG, Knave, Numenera, Savage Worlds, Shadow of the Demon Lord, Technoir, Troika!, and Vagabonds of Dyfed. From the back cover: GroK was once a haven for transdimensional migrants and a bastion of advanced technomancy, until a cataclysm rendered it a desolate hollow planet. Now, feral monstrosities haunt its chasms, cities float among the clouds, and a derelict space station encapsulates the planet and bathes the world in perpetual phosphorescent radiation. Yet, a new era of enlightenment is dawning. Civilizations grow from the ashes, relics of immense power await those who would learn their lost secrets, and threats of caste warfare loom as leaders vie for power. All the while, a creeping black nothingness peers up through the hollow of the world.
