Sidereal Confluence

On first contact, Sidereal Confluence is a little intimidating: cards, chits, and tokens everywhere, as if someone opened the garages of six alien civilizations at once. Take a deep breath, though, and the picture clears up quickly. Beneath that overwhelming first impression sits a brilliant social game, much simpler than it looks and built for big, noisy tables.

Each player takes control of a species with completely different powers and starting production. Across six rounds, you try to make your production engine more efficient, so you have more resources for research and the other ways of collecting points. The species come with different difficulty levels, so a less experienced player can sit comfortably beside someone who wants to wrestle every round with managing their fleet capacity.

The heart of the game is real-time trading. Everyone bargains simultaneously, exchanging almost anything — even technologies belonging to their civilization — to arrange better deals and production. That is where the tension comes from: an offer rejected five times can suddenly be accepted when circumstances change, while overly aggressive bargaining or endless analysis paralysis can choke the pace. There are ways to overcome an embargo, but with only six rounds there is not much room to fix it comfortably.

I had such a good time in my first game that I would have played it again immediately. Even with a sneaky investor sitting to my left, the time vanished. My only substantial complaint was that five players felt too few: with six or seven, more resources and more trading opportunities open up, and the table finds it easier to dare the big, efficient deals. It is one of my best games of the season, and it will be a permanent recommendation whenever a big group gathers. If two-plus hours feels too heavy, it also has a smaller sibling.

Updated session

The second encounter confirmed that exact impression. At a large gathering, Sidereal Confluence was the game I most wanted to play: two hours of hard bargaining is a much better way to get to know new people than yet another party game, because there is real substance here as well. Its length felt right to me; if you want it noticeably shorter, you are probably looking for a different kind of game.
