the settlements in the star trek version are outposts, and when you upgrade them to cities you put a disk on top of them to create a starbase. roads are spaceships (all are a model of the USS Enterprise). the robber is a klingon bird of prey, and the knight is different in that you cant look at your opponents hand while taking a card. their is also the option of playing with support cards. these cards have a main character on them and give you certain bonuses in the game, but can only be used a maximum of two time before you must trade them in. example, Kirk allows you to ignore the 7 card rule from when the bird of prey strikes. and so on and so forth. its really fun, i like it better that the original, not only cuz its star trek, but its more fun im my opinion.
