Kind of kiddish, good on the road tho.
As with other Guitar Hero games, the player attempts to follow the lead guitar portion of a rock song as note patterns scroll by on the game's screens. Instead of the normal guitar peripheral used in other game console versions, On Tour is packaged with the "Guitar Grip", a unique four-fret controller that fits into the Game Boy Advance slot on either the Nintendo DS or DS Lite hardware. The player strums each note by dragging the stylus across the touchscreen while holding down the fret buttons. The design of the Guitar Grip and other gameplay mechanics went through many iterations by Vicarious Visions before the final design was reached. A special Guitar Duel mode against the computer or human opponent over local wifi incorporates other features of the Nintendo DS in order to remove distractions created by the opponent in order to keep playing the song.
On Tour received mixed reviews from critics. Many reviews cited problems with holding the Guitar Grip in place and cramping by holding the Grip too long. While some felt the game captured the spirit of the Guitar Hero series, others felt it was more an experiment than a successful game. The game broke Activision's sales records for the DS the week of its release, and it has been announced that a sequel, Guitar Hero: On Tour Decades, will be produced.
