If there's one thing geeks love, it's customization. The mod culture, the DIY culture, they both run very strong in the geek community. TreeHouse and IceHouse pieces fit right into that niche. One TreeHouse set, and you've already got a variety of games with the ability to create more. More TreeHouse sets, and you've got the ability to tap into the vast DIY culture that is IceHouse. From custom-made pieces to unique fan-created games, every aspect of the system taps into the dig-in-and-do vibe that most geeks have in spades. Nearly all the Looney Labs games tap into that same aesthetic -- Fluxx, Chrononauts, NanoFictionary, they don't only allow for customization, they practically -ask- for it. The open-source geeks will love the idea of being able to write and wiki any kind of games they like! There's also the collector's aesthetic that most geeks love -- TreeHouse/IceHouse in particular lends itself to the Dragon Dice / Magic: the Gathering player's habits, but a complete set can be had without breaking the bank! And the bonus is that customized or out of the box, the games are just as engaging for the family and friends of geeks. Fluxx in particular makes a great party game for everything from kids birthdays to family Thanksgiving, late-night college fests and low-key nights at home. The rules are usually 'a moment to learn, a lifetime to master' and because they're very down to earth and tech-simple themselves, they lack any stigma that some other 'geek' games have on them.
