This is an AI-driven space trading & dynamic world RPG. You travel across 150+ planets in a dynamic universe with 600+ intelligent NPCs. Start as a novice trader, run your own shop, build a powerful trade guild, and become a major player connecting factions across the galaxy. The economy and world are driven by AI. Supply, demand, and prices are not fixed but shaped by the stances, relationships, and choices of NPCs. Trading isn’t just about making profits; it’s about reshaping civilizations.
Break free from linear storytelling and explore different life paths. You can play as a rookie trader, profiting from buying low and selling high; or manage a trade guild, optimize trade routes, and oversee your staff; or become a tycoon allying with military powers. You can also freely explore and write your own legend in this AI-driven, dynamic universe.
Anticipate and influence what’s to come. In the cycles of Neon River, prophecies reveal signs of wars, disasters, and market crashes. You can adjust your trade routes and alliances accordingly — or try to defy the prophecy by changing NPC decisions and Neon River’s future. Every glimpse into the future is an opportunity to rewrite destiny.
Every choice you make truly matters. Over 600 NPCs are AI-driven, each with its own identity, long-term goals, and decision-making logic. They react to your actions, market changes, and faction relationships, influencing the trade networks, power structures, and evolution of this universe in real time.
Not a single number is fixed here. Prices respond to real-time changes by AI. From simple fluctuations caused by trading popular goods, to planetary-scale economic shifts triggered by building trade routes, and even market shocks sparked by disasters or wars, the economy is a dynamic system full of changes.
A unique gameplay fusion of resource management and permadeath. Establish frontier outposts from scratch in mysterious wormholes, allocate populations, upgrade facilities, and unlock tech paths with limited resources and time. Random events, periodic stellar storms, and other unknown crises challenge you to constantly adapt your plans and find the optimal path for survival and expansion.
