Star Wars: Rebellion is the asymmetric game that most captures the feel of its source material. The Rebel player is hiding their base while building a resistance. The Imperial player is building an overwhelming military while trying to find the Rebel base. The information asymmetry is perfect — both players have real agency in pursuit of genuinely different victory conditions.
The Rise of the Empire expansion adds new mission cards, leaders, and a miniatures upgrade that improves the component quality. It is worth adding once you have played the base game to familiarity.
The game length is substantial — three to four hours for experienced players, longer for beginners. For groups committed to the experience, it is one of the most thematic and satisfying games in the hobby. It sits in a specific niche that nothing else fully occupies.
