Sidereal Confluence

WizKids • 2017

Each player controls one of nine alien races, each with a completely different economy. Your race has converter cards that turn input resources into output resources — but you probably can't produce the inputs you need. So you trade. Trading happens simultaneously and in real time. There are no turns during the trade phase. Everyone is negotiating at once. "I'll give you three white cubes for two green." "I need a colony ship — who has one?" "I'll swap you my small converter for your large one and throw in two cubes." Deals can be anything. Any resource, any promise. After trading, everyone simultaneously runs their converters, produces new resources, and scores points. Then a new set of technologies becomes available through a shared bidding system. Repeat for six rounds. The asymmetry is deep. The Kt'Zr'Kt'Rtl (yes, that's a name) have a biological economy that literally grows. The Faderan have intellectual technologies that create resources from nothing but need other races' outputs. The Yengii are good at pure trading but produce little on their own. Each race needs different things from different races. This is a heavy game. The teach takes 30-40 minutes. First-time players will be confused for the first two rounds. But the trading is so inherently social — it's literally just making deals with people — that most groups find the energy even through the learning curve. Plays 4-9. The 9-player game is the full experience — every race at the table, maximum trade options, maximum noise. Games run about 2 hours. It's one of the very few heavy strategy games that actually gets better with more players.
