Eventually, I came across the Looney Labs booth and after a demo (or two, or three) from the Mad Lab Rabbits, I picked up a deck of Fluxx. It was like crack in a cardboard box. So addictive was this game that even our D&D group stopped rolling the dice and flipped cards for a few weekends instead. And that says a lot.
Looney Labs is an independent game company founded by Andrew Looney and Kristin Looney. Fluxx, the card game with ever changing rules, is just the beginning of the Looney Labs addiction. It's a fine game to start with. I mean, it did win a Mensa Mind Games Select award. But then you might want to pick up a stack or two of pyramids and a rulebook for endless strategy gaming. You can even time travel with a deck of Chrononauts or roleplay with a deck of Are You A Werewolf? Now that I live with someone who doesn't love games as much as I do, I really appreciate that a few of their games can be single player too. If you come across their stuff in a retail store, pick something up. Any of the games will do because they are all highly creative. Then once you're hooked, visit their website and buy more.
