Brett Leavy is on a mission to re-create Brisbane.

The Brisbane that existed before roads, bridges and white settlers, in a time where the city's major campsites existed in places like West End, South Brisbane and Bowen Hills.

Mr Leavy is building a role-playing game that simulates the life of the indigenous people and requires players to hunt, gather, explore and perform tasks to gain the respect of local tribes.

He's using topographical data to replicate Brisbane's landscape, has characters based on real-life indigenous figures, and will use 3D modelling to re-create artefacts.
