Sidereal Confluence
Trade resources in real-time as wildly different alien species
Who it's for
Groups of 5-9 who want a loud, energetic evening of negotiation and economic puzzles. Best when everyone leans into the chaos.
Not for you if…
Not for quiet groups, introverts who dislike simultaneous shouting, or anyone wanting a relaxed pace. Needs at least 4 and shines above 5.
Vibe's take
Chaotic, loud, cerebral, exhilarating

About this game
Real-time trading and negotiation game where asymmetric alien species convert resources through production networks. Everyone trades simultaneously at the table — shouting, bartering, and bluffing — then resolves their economies. Scales impressively from 4 to 9 players.
