SETI: Space Agencies

Worth it

Our take: BGG 8.85 from 2,354 ratings (base game 8.41 from 22,593). Reviewers praise the new aliens and cards; some find the organizations forgettable and the Quick Start feels like skipping the opening, and the game is not shorter.
What you need first: Just the base game

What it adds: 11 asymmetric organizations, 3 new alien species, 42 new project cards, 21 Quick Start cards that replace the first round, and signal tokens that help scanning.
What it fixes: Quick Start cards replace the slow opening round.
