The Alternate Universe set. This set brought in a whole bunch of new concepts into the game. Everything there but the non-basic skills.
The Q-Continuum set. This brought some of the most useful cards in the game, like Q's Tent and Q's Planet. The basic skills are here, not the special skills.
The Premium Cards skills list. These cards are from the Federation and Klingon Two Player games and the personnel from the First Anthology.
The First Contact skills list. (IT FINALLY CAME OUT!!!!!).
The Kivas Fajo Collection skills list. I finally got mine!!!
