Every Epic Game starts with a big idea

Why We Created Big Idea Gaming

Big Idea Gaming was founded to bring the creativity of David Barrentine under one roof. We wanted a place that could serve as the home of the World of Oranth setting while also showcasing the creative services behind the work.

As our projects continue to grow, it has become clear we need a central hub for visitors to explore the World of Oranth, discover our TTRPG books and games, and learn about the creative services we offer. Big Idea Gaming showcases our cartography, layout, writing, art direction, game design, and graphic design in one place.

Whether you're here to explore the world we've created, browse our publications, or collaborate with us on your own creative project, we're glad you're here. Welcome to Big Idea Gaming.

Step Into the World of Oranth

Knights of the Shadow Realm -- Digital Copy
$20.00

Conflict is growing near the kingdom of Kalorr but something far worse is happening inside the city walls. Reports of children going missing from the slums have started to spread. Many believe they are looking to join the conflict, others believe they have run away, but something darker is at play here. Investigating the disappearance of a recently missing child finds a trail of clues that threads together a sinister plot. 

This isn't the only issue that plagues Oranthos. Adventurers with friends that have met an untimely death are starting to find resurrection magics no longer hold the strength they once did. Those brought back now speak of a menacing behemoth waiting in the world beyond. Tendrils of darkness corrupt the souls of the recently departed, growing their numbers for something unknown. 

It now falls to the brave to navigate the feuding between nations and uncover clues to a greater threat hiding beyond the veil of death.
