I had never played Fluxx before, and probably never would have were it not for this Oz version. That definitely sold me on it. It truly is the game of "ever changing rules", which can take a little time getting used to. The basic premise is easy to understand, its just drawing cards and playing cards. However, Its not easy to explain the depth the game can reach without visuals or actually participating. On our first round, my friends became sort of frustrated with learning the rules and I was worried they would lose interest. Soon though, everyone got the hang of it and had a ton of fun. The OZ theme is awesome, colorful, and well thought out. I would have no problem purchasing Other Fluxx games if they had similar themes (though not many of the ones currently availible interest me much). An expansion for this would also be wonderful! An interesting feature that I should mention is that anyone can join the game at any time, making this great for family gatherings and holidays. Even if the game has been going for 20 minutes, new players can jump right in. I think small children, say under 8, might have a little troubling playing. There is also a lot of text written on some of the cards and can sometimes take repeated readings to understand. If you've never played fluxx, but like card games and OZ, you can't lose. I've heard from other gamer friends, that OZ and Zombie Fluxx are the favorites. I can see why!
