Green Ronin Publishing is an independent tabletop roleplaying game publisher celebrating 25 years of award-winning games. Its Atomic Think Tank is a subscription-based community created for people who enjoy tabletop roleplaying games and want to connect, learn, create, and play together. The community offers a generous Forever Free access tier, alongside other subscription options, making participation available at different levels.

The Atomic Think Tank supports organized play and gives members a place to share ideas, playtest new concepts, and develop original roleplaying games. It also offers opportunities to learn skills from experienced tabletop game developers and pursue the goal of publishing a game. Members can create new heroes, exchange adventures, and meet others who share their interests.

Rather than focusing only on games and publishing, Green Ronin’s community emphasizes collaboration and connection among players and creators. Through the Atomic Think Tank, the publisher brings together gaming enthusiasts to explore ideas, build creative skills, and take part in shared tabletop roleplaying experiences.
