Sidereal Confluence

Real-time alien trading, no attacks

BGG: boardgamegeek.com/boardgame/202426

Sidereal Confluence is a medium-heavy game (weight 6/10). It offers a substantial decision tree (8/10) — enough to reward repeated study. Decision density is intense (8/10) — expect brain-burn and the occasional bout of AP. Interaction is maxed (10/10) — every turn shapes what your opponents can do. Direct attacks are minimal (1/10) — the friction comes from contention, not aggression. And table-talk diplomacy is essential (negotiation 10/10) — winning requires persuasion.
