Is there any cool reviews or videos of the game play i could check out? My phone is dead at the moment but i'll be sure to check this out when i get a new one.
This project is about an in-time quest in real time. Phone is needed for navigation
Phone is needed in any case. Without a phone you cant play any quest as there is navigation and all interesting tourist places will be marked.
Today, almost every person has a smartphone. So I don't think that this is some kind of problem.
