Raph Koster’s career spans the evolution of the modern MMO. As the creative lead on groundbreaking titles like MUDs, Ultima Online, Star Wars Galaxies, and EverQuest II, the systems and mechanics his teams developed continue to influence every active MMO today and many games beyond. Reflecting on his journey, Koster humorously notes, “People made fun of me for having dancing in Galaxies. Fortnite ought to give me royalties.”
However, Koster’s latest project, Stars Reach, promises a scale surpassing all previous endeavors. This sci-fi MMO is set in a procedurally generated universe, where each world serves as a sandbox comprising materials that adhere to real-world physics. Players have a range of interactions at their disposal: freeze a lake to create an ice rink, boil it to produce steam for machinery, or electrify salt deposits to generate chlorine gas.
While Stars Reach features an overarching narrative about an invading alien force that materializes through emergent events, prompting players to unite against the enigmatic “Cornucopia,” Koster’s focus during our discussion centered on the underlying sandbox mechanics that define Playable Worlds’ MMO.
Koster emphasizes that the game’s richness grows with the depth of its underlying simulation. He states, “All of the game gets richer, the more the simulation underneath is present.” The aim is to construct a consistent physics simulation across all planets within Stars Reach, ensuring that interactions feel natural and intuitive. Players are encouraged to experiment and apply knowledge from their experiences outside the game. For instance, variations in climate and irrigation can lead to transformative effects on environments, such as turning a desert into flourishing farmland.
In a recent demonstration, Koster illustrated these mechanics as a player drilled into the bank of a mountaintop lake, resulting in a cascading waterfall that turned the surrounding earth into mud. He recalled an incident where players attempting to build a city on a planet called Gaiamar unintentionally created flooding when a water feature malfunctioned, leading to significant structural collapses in player-built homes.
Koster draws comparisons to other games where physics applications can feel inconsistent, resulting in moments that disrupt immersion. In Stars Reach, the goal is to maintain a coherent world where interactions feel organic rather than scripted. Players will find that their tools, such as the unique “Chronophaser” used to age materials, encourage innovative problem-solving within the game’s environmental context.
While the physics system is pivotal, the graphical presentation may evoke memories of early 2010s MMOs. However, Koster clarifies that Stars Reach aims for a fundamentally different experience. Unlike scripted animations in titles like Helldivers 2, where effects are predetermined, Stars Reach allows for dynamic environmental changes that can lead to unique and unforeseen consequences based on player actions.
The procedural generation technology that underpins Stars Reach draws inspiration from Conway’s Game of Life, wherein simple rules govern the emergence of complex behaviors. Koster explains that by adapting these principles to a 3D environment, players will experience interactions among diverse elements that mirror real-world phenomena. Rather than limiting interactions to binary states of “alive” or “dead,” Stars Reach’s world incorporates various materials, each with different properties and reactions to environmental factors like temperature and humidity.
Koster notes that creating a fully interactive world has required years of development and experimentation. Unexpected bugs can arise from the world’s complexity, illustrating the challenges of maintaining a cohesive simulation.
With advancements in computing power and cloud technology, the kind of immersive, physics-driven world Koster envisioned has become feasible. Stars Reach boasts an intricately populated landscape, powered by millions of individual agents that apply the game’s physics rules, thus enabling a vibrant and reactive world.
Koster concludes by expressing the desire to create worlds that feel profoundly immersive and alive—offering players not merely a challenge to gather loot and level up, but an experience filled with wonder and dynamism. In demo sessions and player streams, Stars Reach has showcased a community-building aspect as players collaborate to shape their environments, establishing towns and transit systems amidst the novel gameplay.
In a landscape where MMO innovation has stagnated, Stars Reach is positioned to stand out, offering a fresh approach to the genre and an inviting promise of a living world.
