Players collect and trade these resources – dilithium, tritanium, food, oxygen and water – in order to build Starships that connect regions in the galaxy, establish more Outposts and Starbases (upgraded Outposts) at new intersection points in order to increase resource acquisition, and acquire Development Cards that provide Victory Points (VPs) or special abilities.
On a dice roll of 7, a Klingon ship swoops in to prevent resource production on one planet while taxing spacegoers who hold too many resources.
Star Trek: Catan differs from the basic Catan in one aspect: a set of Support Cards. Each Support Card features a special ability and one of Kirk, Spock, McCoy, Sulu, Scott, Uhura, Chekov, Chapel, Rand, or Sarek. Some special abilities make basic actions better, such as reducing the costs of Starbase upgrades or allowing the player to trade a resource of their choice at 2:1 for a turn, while others break rules, such as protecting the player from discarding on a 7 or producing a resource when the player rolls a number that wouldn't otherwise produce for them. Players get a specific Support Card during setup based on turn order, with later players getting generally more useful abilities to compensate for early player advantage.
