Greenheart Games

Greenheart Games is an independent Australian game developer and publisher founded in July 2012 by brothers Patrick and Daniel Klug. Based in Brisbane, the studio creates simulation and strategy games, working with a distributed team and international specialist contributors. Its original projects explore business management and fantasy tavern simulation.

Games and development

The studio’s debut title, Game Dev Tycoon, places players in charge of a game development business. Its release history spans Windows in 2012, followed by Mac, Linux and Steam in 2013, with later adaptations for iOS, Android, Nintendo Switch and Netflix Games. These releases brought the studio’s business simulation to desktop, mobile and console audiences.

Its second original intellectual property, Tavern Keeper, focuses on fantasy tavern management and sandbox simulation. Following an extended development cycle of roughly a decade, it entered Steam Early Access on November 3, 2025. Development continued through 2026 with major system updates and decorative expansions. The project became the focus of the studio’s multi-year development effort; the company clarified that a direct sequel titled Game Dev Tycoon 2 had not entered production.

Capabilities and publishing

Greenheart Games combines game systems and narrative design with independent development and self-publishing. Its reported capabilities include cross-platform optimization, save functionality and cloud integration. The studio also collaborates with external developers to adapt its games for additional platforms. Austrian partner Rarebyte handled mobile and Nintendo Switch adaptations of Game Dev Tycoon, along with its Netflix Games release.
