Grab Your Tin Foil Hats, Martian Fluxx Is Coming! by Jonathan Liu
"Fluxx is one of my favorite games, especially because my wife also loves it and I can usually convince her to join in for a game or two. It's a card game where the only thing constant, as they say, is change. In Martian Fluxx, you actually play the Martians (unlike Zombie Fluxx, in which you're the humans battling the zombies). Keepers include things like the Tentacle, or Cow, or various bits of Martian technology. For a portable game that's easy to teach and unpredictable fun, the Fluxx series is a great one to check out. I'll have to give it some time before I decide if I like the zombies or the Martians better, but if you like sci-fi then Martian Fluxx might be the one for you. "
