Dark Sky is a focused mix of card combat and more classic role-playing. The science-fiction universe is varied and interesting, although it’s sometimes hard to connect with the characters. All combat is tense, and players have to pay attention to enemy force composition and develop strong strategies around card synergies. It’s possible to breeze through normal encounters, perhaps with a revive or two, and then get stuck on a boss for an hour, which in turn can generate frustration. But for fans of card-focused combat with a strong deck-building focus, Dark Sky is a great experience that will test their skills and reward them with plenty of complex engagements.
