Guitar Hero 7 was a game that existed, at least in a development phase, until Activision canceled it in early 2011, Kotaku reported, citing an anonymous source.

Guitar Hero 7 had only a guitar, ditching the drums, mic and bass that surfaced once Rock Band entered the market. The guitar saw some changes, however, and had a full six strings and an extra button in the neck. It was expensive, unresponsive and development was, overall, a "disaster," Kotaku said.

Vicarious Visions, the team in charge of developing Guitar Hero 7, had some great ideas about creating a morphing, unique music video for each song. The songs themselves posed a problem: "The game had all of the worst hits from the 1990s," Kotaku wrote, quoting its source. "They realized that, with our lack of budget and time, they couldn't get quality music so they bought bargain-basement music like 'Closing time' and 'Sex and Candy.' There were some songs in there that had been used at least three times in the GH franchises before."

The music video idea quickly became unwieldy, too, and development fell apart. Guitar Hero 7 was canceled in the middle of an expected two-year development cycle. Just think, we could have had a new Guitar Hero on our GOTY lists this year. Maybe.

Maybe not.
