Poor Guitar Hero. All they want to do is show cartoons of rock stars bouncing around and having fun, and now everyone's gotta get all uptight about it.

Courtney Love and Dave Grohl love money more than their dead husband and bandmate, so Love let Activision include his image and Grohl let them use his music in Guitar Hero, where people make him sing Bon Jovi songs.

CARLSBAD, CA — On stage at D6, Sue Decker couldn't offer any explanation why she was qualified to be president of Yahoo. But if you ask Valleywag, she's doing a bang-up job of pursuing Yahoo's strategy of embracing openness. For example, by holding a meeting within camera-lens length of Valleywag in the Four Seasons Lobby Lounge. Our eye was first drawn by Yahoo Media Group chief Scott Moore's blindingly colorful Madras shirt; we then saw he was sitting with Decker. Two of the other participants: Gordon McLeod and Matthew Goldberg, business-side executives at Dow Jones, which means they were likely discussing some kind of news-content partnership between Yahoo and the Wall Street Journal. I'd thought I spooted Brad Garlinghouse, the Yahoo executive who wrote the famous "Peanut Butter Memo," in the group, but I'm told he wasn't there. I later spotted him strolling down the halls with Yahoo board member Bobby Kotick, the CEO of Activision. More pictures of the meeting:

The merger between Vivendi's games division and Activision is a big deal in the videogame business. The industry's Davids now have not one but two Goliaths to sling stones at. More importantly, console makers have two equal-sized publishers to play against each other. But it wasn't Activision CEO Robert Kotick's dream of forming a company to rival Electronic Arts that convinced him to form Activision Blizzard with Vivendi — it was World of Warcraft. According to accounts in both the New York Times and the Wall Street Journal, Kotick was "eager" to get into online games — multiplayer online worlds are all the rage right now.

Vivendi is forking over $1.7 billion to take a controlling stake in videogame publisher Activision. With their powers combined, they'll create a new game-publishing goliath, Activision Blizzard, ostensibly worth $18.9 billion. In size, it will rival longstanding industry leader Electronic Arts. The deal pairs Vivendi-owned Vivendi Games and Blizzard, the folks behind online multiplayer game World of Warcraft, with Activision's portfolio of Tony Hawk-licensed skateboarding games and Guitar Hero.

Despite Internet entrepreneur Mark Cuban's tenacity on Dancing With the Stars and his status as Silicon Valley demigod, he is not considered a "who's who" by Activision. He's been left out of the videogame publisher's Wii and PlayStation 2 titles based on the ABC show, which allows you to fulfill your most nerdly ballroom-dancing fantasies in the privacy of your own living room. But sadly, Cuban's hot-trotting shoes and puppeteer-spontaneous jazz-finger outbursts are not part of the package. Instead the adaptations stick you with the likes of Emmitt Smith and Joey Lawrence.

Amidst all the hubbub about MediaDefender — the file-sharing policing agency whose private email files were recently spewed across the Internet, revealing unsavory antipiracy plans — one particularly interesting tidbit has bubbled to the surface. The Pirate Bay, a major file-sharing site, says it now has proof from those files that the music and movie industries have been paying hackers to attack the site. It is now taking this information to the police and charging the Swedish arms of Fox, EMI Music, Universal, Paramount, Atari, Activision, Ubisoft and Sony with technical sabotage, denial-of-service attacks, hacking, and spamming.

CONFONZ — When it comes to making software, it's Q/A that really sucks. The job is totally thankless. As if this weren't bad enough, there is a distinctly finite amount of actual programmers in the games industry, and they all know each other. And, more importantly, they all know the ones that stink. Those stinky programmers still get jobs, though, and it looks like Activision managed to hand off the engine development duties for its Spider-Man 3 movie game to some numbskulls that didn't understand the RAM constraints of the various consoles. After the jump, the gory details, as told to the ConFonz over web-covered beverages.
