Guitar Hero
In 2015, Activision announced the first new title to the series in 5 years, "Guitar Hero Live", released in October 2015. The title is considered a reboot of the series, with development being performed by FreeStyleGames, who had developed the "DJ Hero" games previously. As of December 1, 2018, Activision disabled the GHTV servers for Guitar Hero Live, reducing playable content from approximately 500 songs to 42 on disc tracks.
Guitar Hero: On Tour series
"Guitar Hero On Tour: Decades" was announced on July 15, 2008, at the 2008 E3 conference, and released on November 16, 2008. Executive Producer David Nathanielsz stated that the short time between releases was to help give DS players the same depth of content as available to the console players of "Guitar Hero". Additionally, Vicarious Visions incorporated the ability to share songs between different versions of the game through the wi-fi capabilities of the DS in order to expand the number of potential songs to more than 50.
