Review copies of Electronic Arts's Kingdoms of Amalur: Reckoning are starting to reach critics, who have made a surprising collective discovery: an insert containing a code to download a "House of Valor" content pack featuring "seven additional single player quests."

EA has confirmed to Ars Technica that this downloadable content will be included free with all new copies of the game, including digital copies purchased on the PC through Origin, Steam, or other services. Players who would rather purchase a pre-owned copy, however, will presumably have to pay an additional fee if they want to access to this portion of the game.

Charging used game players for such an "Online Pass" is nothing new in the game industry, of course. But implementing an Online Pass in the single-player Kingdoms of Amalur represents a continuing tumble down a slippery slope for the entire game industry.

Kinect's vision and depth perception technology could soon be integrated into laptops. The Daily has seen two prototypes, believed to be from Asus, that incorporate an array of sensors above the top of the screen, replacing the traditional webcam. Below the display are a set of LEDs. Sources at Microsoft confirmed to The Daily that the laptops contain versions of the Kinect sensor.

Asus has dabbled with Kinect-like systems before. Its Xtion PRO PC peripheral uses sensor and software technology licensed from PrimeSense—technology also found in Microsoft's Kinect sensor.

What the sensor might be used for is anybody's guess. The Kinect for Windows—a version of the Xbox 360 accessory with revised firmware to support close-up operation—will be released in February, and with that, third-party applications that use the sensor will start to arrive. Windows 8 might even include direct support for Kinect-powered features: documents leaked in 2010 hinted at Kinect integration with automatic user switching using face detection.

On almost any given day, Twitter receives a handful of requests to delete tweets that link to pirated versions of copyrighted content—and quickly complies by erasing the offending tweets from its site.

That fact itself is probably unsurprising to people familiar with the Digital Millennium Copyright Act (DMCA) takedown process, which gives sites like Twitter a "safe harbor" against lawsuits related to user behavior and uploads—so long as the sites don't knowingly tolerate pirated material or links to such material.

But Twitter has taken the unusual step of making DMCA takedown notices public, in partnership with Chilling Effects, a project of the Electronic Frontier Foundation and several universities. The site shows 4,410 cease and desist notices dating back to November 2010. While most of 2011 shows daily or near-daily activity, there is just one notice in January 2012, suggesting either that Twitter is suddenly receiving fewer DMCA takedown notices or that the database is not quite up to date. (If we find out from Twitter or Chilling Effects, we'll update the story.)

Hewlett Packard is showing off a range of new printers at Macworld|iWorld 2012, largely aimed at the home office and small-to-medium business segments. However, a new feature of its latest printer models is what really caught our eye on the show floor. HP's Wireless Direct makes it possible to print documents and images from an iOS device via AirPrint without even knowing the name or password of the local wireless network.

All of HP's printers now include the company's ePrint feature, which enables options like wireless printing, sending documents to print via e-mail from anywhere in the world, and directly accessing documents in the cloud. These ePrint capabilities also enable support for Apple's AirPrint standard, according to Marketing Manager Annamaria Pardini, which lets iPhones and iPads to print to a networked printer without any setup, configuration, or driver installation.

The rise of purely digital online game sales has changed the industry in a number of ways, but the most important change might be the introduction of games as impulse buys. Anyone with a credit card tied to their Steam account knows how scarily easy it is to, with just a few clicks, dump more money than you intended on a whole passel of games that seem vaguely intriguing. You might not have read any reviews, or even heard anything about the game outside of the Steam description, but when it's so cheap and the purchase process is so seamless, your consumptive id can often act before your conscious brain even has a chance to question whether you really want the game you're buying.

Digital stores on platforms from Sony, Microsoft, Apple, and Google have similar setups to encourage this kind of impulse purchase—enter your credit card once, then buy with a few clicks forevermore. Nintendo is the lone holdout, as it often is with online features, refusing to store credit card information for users with a Wii or 3DS. But that might change in the next console generation, with Nintendo President Satoru Iwata announcing today that the Wii U will use near-field communication technology "as a means of making micropayments."
