The Journey, a freeware location-based interactive game for S60 from 'the old days' has just been made available in Symbian Signed form for S60 3rd Edition (and looking very natty on the E90). Here's The Journey download page.

"The Journey is a new and unique adventure game experience for your mobile phone. You are in the role of an infamous detective and have to solve a mysterious case not only by making it through the story, but also by walking to different locations.

Gone are the days where you watch a virtual character moving around on your display. Now you have to move yourself. The game is aware of your movement. Right at the beginning when you as the detective have to leave your bureau and go outside, you have to take your mobile and go through the streets of the city you live in.

The game saves the locations and in the course of the story you will have to return to your bureau and walk back to the place where you started playing."
