Holiday Gifts
A few people have asked me what gifts I think gamers might want. That's pretty hard to answer, but I'll try. First, gamers want Sirlin.net merchandise (also here) like T-shirts, mouse pads, or a Yomi tie.
Games
Once that's out of the way, pretty much everyone likes Xbox Live Arcade so a gift card with Microsoft points is a good bet (assuming they have an Xbox 360 to begin with). A gift card will let them buy amazing games like Street Fighter HD Remix, the masterpiece Rez HD, or that new Civilization game. I haven't tried it but I bet it's good.
If anyone is playing Street Fighter HD Remix with a pad, they'd do well to stop doing that and get a joystick. I used these Hori sticks throughout all of Street Fighter's development, and I used one to reach #1 on the ranked leaderboards. I hear some people complain that this stick isn't good enough, but apparently it is! I've also heard people complain that the buttons break, but I've never had a problem with any of my hori ex2 sticks, so maybe I'm just extremely luckly. You could always hold out for this higher quality real arcade pro hori stick, but it won't be a holiday gift anymore.
Everyone seems to like these shooting games, and this RPG. But don't forget about Wii games. For actual gamers, Mario Galaxy and Resident Evil 4 are still as awesome as ever. I haven't played the new Lego Indiana Jones, but I loved the first Lego Star Wars and people tell me this one is even better. It can really bridge the gap between gamers and non-gamers (hint, play with your girlfriend). And things like Wii Music and Endless Ocean will also get non-gamers involved. [Edit: Wii Music is probably best for kids, while something like Guitar Hero is probably better to rope in adults.] There's also Wii Fit of course, but it's really hard to get right now.
Or some cocaine would be another way to go. You can even give the addicts a 2-month dose.
Computer
As some general life advice, I recommend not using Microsoft Windows anymore. The most amazing material good that I have ever owned in my life is a Macbook Pro. It's a magical wonderland. No viruses exist for Mac, so there's no need to muck around with anti-virus software. The OS isn't DRM crazy like Vista, so it doesn't check all my hardware components 30 times per second to see if I have connected a device that might try copy DRM video. Above all else, it really does "just work" and have so many nuances of software design that are wonderful. It's also amusing that I can't even figure out how to network my two old PCs, yet my Mac can automatically see both of them and transfer files between them. So yeah, try out those new Macbook Pros that are even better than mine (get 4 GB of RAM so you can have 50 things open at once like me). They make them out of a single piece of carved aluminum these days, so even construction-wise they're pretty amazing. And you can run Windows on them too, in case you're developing a game with some bad person who keeps making a Windows-only version.
The 13" Macbook is even cheaper, and also worth every penny.
Books
Books can change the way people think. Last year, I gave Flow and Blink as gifts to several people. Blink is a little more entertaining, but Flow is a little more important. Flow describes an important psychological state that we feel when we are challenged and it's tied to the process of achieving mastery AND plays in to people's overal, general happiness, if you can believe that. Blink shows the tip of the iceberg of the idea that we make decisions by only consciously knowing about tips of icebergs, yet those decisions are often very good. These books are important enough that it scares me that these subjects aren't regularly taught in school.
Gladwell (author of Blink) also has a new book called
