Which studio developed the Guitar Hero: On Tour series?

Vicarious Visions developed the Guitar Hero: On Tour series.

The series brought Guitar Hero to Nintendo DS handhelds, beginning with Guitar Hero: On Tour in 2008. Vicarious Visions created the games and developed the distinctive Guitar Grip, a peripheral that plugged into the DS or DS Lite’s Game Boy Advance slot and provided four fret buttons.

Players strummed across the DS touchscreen with a stylus while holding the system with the grip. Designing that control method required extensive experimentation: the studio tested more than 20 hardware and software combinations before settling on the grip-and-touchscreen approach. Nintendo and RedOctane assisted with hardware interaction and ergonomics.

The On Tour line included the original game, Guitar Hero On Tour: Decades, and Guitar Hero On Tour: Modern Hits. The grip is incompatible with the Nintendo DSi and later 3DS hardware because those systems lack the required Game Boy Advance cartridge slot. Activision published the series.
