If you know anything about Lovecraft or the Cthulhu mythos (which I'm assuming you do because you are on this page) you know that Lovecrafts works have an overlying theme of chaos, madness, and insanity. That theme fits extremely well with Fluxx! The rules can change in an instant and you really cannot predict how the game will go, which makes it very replayable. I suppose you could also think of it as Calvinball the card game. It also manages to feel very Lovecraftian (unlike some other themed versions of games that feel identical to the originals only with different characters). I've only played it with two people, but I can imagine that it would be just as fun, if not more so, with a lot more. Games last anywhere from 5 minutes to 45, depending on how the cards fall. The boyfriend and I have been playing this about every Sunday since we bought it, that that was months ago. I would highly recommend this game!
