Tarn Adams, co-creator of Dwarf Fortress, has over 1,400 hours in Factorio and is currently obsessed with terraforming games: 'Dwarf Fortress just doesn't accommodate a full-on sci-fi thing'

Tarn Adams, one of the visionary minds behind the legendary and infinitely complex simulation game, Dwarf Fortress, has recently offered a fascinating glimpse into his personal gaming preferences. Adams has dedicated an impressive amount of time—over 1,400 hours—to the popular factory-building title, Factorio. This revelation underscores a deep personal affinity for intricate systems and optimization, a passion that clearly extends from his own game design philosophy.

Beyond his extensive ventures into constructing efficient production lines in Factorio, Adams' current gaming obsession has shifted towards terraforming games. This deep fascination with the grand-scale manipulation and transformation of planetary environments resonates with a core aspect of his work: the creation and evolution of intricate worlds. While Dwarf Fortress excels at organic, fantasy-driven world-building, terraforming titles offer a different, yet equally compelling, canvas for systemic creativity.

When asked about the potential for Dwarf Fortress to explore more futuristic or science fiction themes, Adams provided a candid explanation. He stated, "Dwarf Fortress just doesn't accommodate a full-on sci-fi thing." This insight highlights the foundational fantasy and mythological framework upon which Dwarf Fortress is meticulously built. Its rich lore, emergent narratives, and established mechanics are deeply intertwined with its high-fantasy setting, suggesting that a complete genre pivot to science fiction would fundamentally alter its core identity and established universe. Such a drastic shift, Adams implies, would likely necessitate the creation of an entirely new game rather than an expansion of the existing Dwarf Fortress universe.

Adams' personal gaming habits offer a unique window into the mind of a celebrated game developer, showcasing his enduring appreciation for deep, emergent gameplay, the satisfaction of building and refining complex systems, and the joy of watching intricate worlds come to life—be it a dwarf fortress, an automated factory, or an entirely new planetary ecosystem.
