Quick Answer

Choose Cthulhu Fluxx if you want a horror-themed deck with a darker, investigative tone and it is available now. Choose Star Trek Fluxx if you prefer sci-fi exploration and can wait for the new print run on 10/20/26, or buy the demo copy if you want the same game immediately.

Theme and Tone: Horror vs Sci-Fi

Cthulhu Fluxx leans into cosmic horror. The supplied catalog facts describe following a wild-eyed Poet, an obsessed Artist, and expeditions investigating Eldritch Secrets, with a stolen Necronomicon and strange transformations. Star Trek Fluxx is a sci-fi adventure featuring Kirk, Spock, and the final frontier. Your choice depends on whether your group prefers dread and mystery or exploration and optimism.

Availability and Timing

Star Trek Fluxx is coming out of the vault with a new print run available 10/20/26. Right now, the only copies are demo copies with a bright pink DEMO COPY sticker on the front. Cthulhu Fluxx is available as a standard edition at the catalog price. If you need a game today and want a clean box, Cthulhu Fluxx is the straightforward pick. If you are a Star Trek fan and can wait, the new print run is just days away from the application date.

Trade-Offs to Weigh

  • Theme: Cthulhu Fluxx delivers cosmic horror and investigation; Star Trek Fluxx delivers sci-fi exploration with Kirk and Spock. Pick the theme that matches your group's taste in stories.
  • Availability: Cthulhu Fluxx is available now; Star Trek Fluxx demo copies are available now, but the new print run arrives 10/20/26. If you need a gift today, Cthulhu Fluxx is the safer bet.
  • Box Condition: Demo copies have a bright pink DEMO COPY sticker on the front, which some collectors dislike. If you want a clean box, wait for the standard edition.

Product Facts

  • Cthulhu Fluxx: Follow the wild-eyed Poet, the obsessed Artist, and the expeditions of the Professor, as they investigate Eldritch Secrets no mortal was meant to discover. Sets a horror-investigation tone that appeals to groups who enjoy creepy themes and narrative flavor.
  • Star Trek Fluxx Demo Copy: Star Trek: Fluxx is coming out of the vault - a new print run will be available 10/20/26. The only copies we have now are these demo copies - it's the same exact game, but with a bright pink DEMO COPY sticker on the front of the game. If you want a pristine box, wait for the new print run; if you want to play now, the demo copy is functionally identical.
  • Little Groot: This promo card works in any Fluxx deck... if all you want it to do is make people say "I am Groot." If you want it to have any function other than that, it really only works in Marvel Fluxx. A cheap add-on for Marvel Fluxx owners, but not a reason to choose between Cthulhu and Star Trek.
