A science-fantasy sandbox MMORPG led by Raph Koster, designer of Ultima Online and Star Wars Galaxies. Features a living galaxy where planets and environments respond dynamically to player actions. Launches in Early Access on PC via Steam in Summer 2026.
Stars Reach is a science-fantasy sandbox MMORPG developed by Playable Worlds, led by Raph Koster, the designer behind Ultima Online and Star Wars Galaxies. The game enters Early Access on PC via Steam in Summer 2026 with three tier options: the Firstlight Pack at $29.99, the Voyager Pack at $49.99, and the Cosmonaut Pack at $79.99.
Stars Reach is built around the premise that every player action has a lasting, measurable effect on the living worlds they inhabit. Planets have simulated ecosystems, matter states, weather patterns, and economies that shift in response to what players do. The design reflects Koster's long-held philosophy that the best MMORPGs are systems for emergent stories, not scripted content delivery platforms.
The game is set across a vast procedurally seeded galaxy of planets, each with distinct biomes, flora, fauna, and resource exports. Players explore these worlds, settle them, exploit them, and leave a permanent mark on their state.
Planets respond to player activity in concrete ways. Overhunt a species and its population collapses, disrupting the food chain and changing what resources are available from that ecosystem. Burn a forest and the land changes. Carve rivers through terrain and water flow redistributes. Plant settlements and the surrounding land shifts to reflect what the population needs. The environment is not decorative. It is a reactive system that evolves based on collective player decisions across the server.
Playable Worlds built Stars Reach around a physical simulation that tracks environmental data at a granular level. The temperature of every cubic meter of the game world is modelled. Every object exists in one of the states of matter and can shift between solid, liquid, and gas depending on how players interact with it.
Water evaporates, forms clouds, and falls as rain elsewhere. Terrain changes persist. The game does not reset its world to a previous state after a server cycle. What players build, destroy, and cultivate accumulates over time into a world shaped entirely by its population.
Stars Reach uses a classless skill system modelled after the depth of Star Wars Galaxies. The current build includes around 40 skills spanning combat, crafting, profession, and social capabilities. Players invest in the skills relevant to the role they want to play rather than selecting a class that locks them into a predefined path.
This approach means two players at the same level of overall progression can play entirely different games depending on which skills they have developed. A player focused on terraforming, resource management, and trading occupies a meaningfully different role in the game's economy from one who has built combat and exploration skills for planet surveying.
Players can construct settlements that grow into cities with functioning economies and governance structures. Roads, farms, markets, and housing are all player-placed. The cities that develop on a planet reflect the priorities and aesthetics of the players who built them.
Governance systems allow player organisations to manage their territory, set trade policies, and coordinate with or compete against other settlements across the galaxy. The political landscape of Stars Reach is entirely player-driven, with no NPC factions controlling territory in the traditional sense.
Each planet in the galaxy offers distinct exploration opportunities based on its biome composition and the resources its ecosystem produces. Players survey new worlds, catalogue their resources, and decide how aggressively to exploit them. Some players will strip a planet for maximum short-term yield. Others will develop sustainable economies that preserve the ecosystem for long-term productivity.
Terraforming tools let players reshape terrain directly. Rivers can be rerouted, coastlines modified, and surface features altered to suit settlement needs or strategic goals. These changes persist on the planet permanently, building a cumulative record of every civilisation that has passed through.
Koster has stated publicly that Stars Reach is deliberately designed to resist being fully solved by wikis or guides. Systems interact in ways that produce emergent outcomes the developers themselves cannot predict fully. Discoveries made by players are expected to be genuinely novel information, not just the first person to publish what a developer already documented.
This philosophy is a direct response to the way modern MMOs have become fully charted experiences where the optimal path through every system is published before most players encounter it. Stars Reach is intended to reward exploration and experimentation rather than efficient consumption of documented content.
Stars Reach is the most ambitious attempt in years to revive the player-driven sandbox MMORPG design that defined Star Wars Galaxies before its controversial 2005 overhaul. The physical world simulation, classless skill system, and persistent player impact on environments combine to produce a game that is fundamentally different in design philosophy from theme-park MMORPGs or progression-focused action games.
Players drawn to sandbox-first MMO design and who want to see how the genre has evolved since Koster's earlier work should also explore the new MMO releases of 2026 for companion titles like Camelot Unchained, which targets a different corner of the sandbox genre with its realm-versus-realm PvP focus.
Raph Koster is one of the most influential designers in MMORPG history. He was the lead designer of Ultima Online, the 1997 sandbox MMORPG that established much of the vocabulary the genre still uses. He later served as creative director on Star Wars Galaxies, known for its radical profession system and player-driven economy before the 2005 New Game Enhancements overhaul. Stars Reach is his return to original MMORPG design after years away from the genre.
Stars Reach shares the same design philosophy as pre-NGE Star Wars Galaxies: a classless skill system, player-built cities, profession-based economies, and a sandbox structure with no prescribed content path. The setting is original science-fantasy rather than licensed Star Wars IP, and the physical world simulation goes significantly further than anything in SWG. Players who enjoyed SWG before 2005 are the clearest target audience.
Yes. Combat is one of the 40-plus skill areas in the game. Players can build combat-focused characters who explore dangerous regions, hunt creatures, and engage in player conflict. Combat is a meaningful part of the game but not the primary progression path. Players who invest entirely in non-combat skills can still be highly effective contributors to a settlement's economy and development.
The ecosystem simulation tracks species populations, resource regeneration rates, and environmental conditions. Overharvesting or overhunting causes measurable decline. If a species is hunted to extinction, it is gone from that planet permanently. Resource nodes deplete at rates determined by how aggressively the player population is extracting them. These are permanent consequences, not temporary regeneration timers.
