"Technical or licensing restrictions" will prevent Wii owners from receiving all of the Guitar Hero World Tour downloadable content that PlayStation 3 and Xbox 360 players can access, publisher Activision Blizzard has revealed.

As the Wii's online Shop Channel lacks the ability to bundle multiple downloads into one purchase--the store only allows songs to be sold individually--some downloadadable content, such as last week's Jimi Hendrix Track Pack, will not be available on Wii.

"Certain artists prefer to keep the integrity of the track pack rather than releasing singles," Activision Blizzard told MTV Multiplayer, referencing the Hendrix pack.

Guitar Hero: World Tour will get a The Killers track pack November 25, publisher Activision announced today.

Containing "Human" and "Losing Touch" from the band's new album Day & Age, and "Mr. Brightside" from their debut album Hot Fuss, the DLC will sell for 440 Microsoft Points on the Xbox Live Marketplace and $5.49 in the PlayStation Store.

Each song will also be available individually for 160 Microsoft Points (Xbox 360), $1.99 (PS3) or 200 Wii Points (Wii).

Rock Band 2 designer Dan Teasdale knows that user song creation may become the next big thing in music-rhythm games, but he found the creative suite in competitor Guitar Hero: World Tour (PS2, PS3, 360, Wii) a bit lacking.

Teasdale wasn't short on details in his explanation to Videogamer.com:

We actually want to find a way to for people to create music and express themselves, but when we do we want to make sure that people can sing, or the songs can be longer than three minutes, or that you can have more than 1200 notes, or that you're not tied to some dodgy sample somewhere. We want to make sure it's an authentic experience and it fits on the platform.

"If you want to do a way to let players create and distribute music, you have to go all-in--not just do it as a bullet on the back of a box," the designer elaborated. "We've dabbled around with stuff like that before, with Frequency and Amplitude, and we learned a lot of lessons from it," he added.

"The main one is that you can't do it half-arsed," Teasdale said.

Following a number of complaints, Guitar Hero World Tour publisher Activision has admitted that a "certain drum kit controllers" are suffering from sensitivity issues.

The company believes the defective kits stem from an "isolated manufacturing issue" that occurred early on, with those affected urged to contact customer support.

Activision also noted that it will soon offer players a "drum tuning kit" to ensure drums are properly optimized, and said it will perform more random quality tests.

Guitar Hero World Tour arrived on PS2, PS3, Xbox 360 and Wii this past Sunday, with reports soon coming in of defective drums and guitars. Today's statement only applies to the drum kit issues--the company has not offered a statement on the guitar woes some report--with the controllers covered under warranty.

Activision's full statement follows:

We have learned that certain drum kit controllers manufactured for Guitar Hero World Tour have sensitivity issues. We believe that these controllers are limited to ones in the earlier manufacturing stages... Read more

Some buyers of Guitar Hero World Tour--which launched yesterday--are complaining of faulty instruments, mirroring the issues that afflicted last year's debut of the Harmonix-developed rival series Rock Band.

Complaints regarding the wireless drum kit focus on drum pads and cymbals that don't register every hit. The wireless guitar has also drawn criticism, with many, such as Shacknews' own GoS-CPT-Stewart and dblagent, finding that the guitars have stopped registering downward strums after a few hours.

Activision's official support forum for the game's instruments are filled with reports of the instrument failure across PS2, PS3, Xbox 360 and Wii--the four platforms that received Guitar Hero World Tour yesterday. In response, the forum... Read more
