About the game
Sidereal Confluence is a trading and negotiation game that brings together 4 to 9 players in a star quadrant where each alien race strives to thrive. The core mechanic is trading resource cubes, ships, and colonies while keeping each economy running and advancing technologically. The game shines with its open trading phase, where anything can be negotiated—from a newly discovered planet to a temporary technology contract. Then all players execute actions simultaneously, keeping tension high and avoiding the monotony of traditional turns. Victory points are hidden, so you never know if you’re on the right path until the end. What really sets Sidereal Confluence apart is the blend of sealed‑bid auctions, shared tech trees, and variable player powers tied to the chosen race. If you enjoy haggling, planning income, and discovering new advancements, this game delivers hours of strategy and social interaction. The visual design is clear, but the learning curve can be steep for those new to real‑time play or hidden resources. In short, Sidereal Confluence is an intense economic and diplomatic space experience that rewards patience and cunning.
