"Based on the people I've talked to, the gaming community is looking for something else, a different perspective from the last 20 years of gaming, which has been largely Japanese and Eurocentric.

Hemopo-Hunuki said the gaming platform was an amazing way to tell a story.
"It's hands-on. It will see people all around the world interacting with these legends and the history of Polynesian and Maori people."
He said the series was hopefully just the beginning of a multimedia franchise.
"The game comes first but then we want to look at an animated series, movies, figurines - the possibilities are endless."
The target audience would be mature gamers, because of some of the "dark story lines".
Titans of Aotearoa was one of three Rotorua projects to be given the green light by Te Puni Kokiri and Waiariki MP Te Ururoa Flavell.
The other two projects were the production of a digital cartoon in te reo Maori and programmes through Digital Natives Academy aimed at helping build digital pathways for Maori.
