Urbax is a role game involving the main actors in urban development and planning: a city council, a public housing agency, private developers and industrialists. It is a computer assisted simulation in which the software program is only an aid and does not assume the simulation by itself (contrary to video games). The simulation is done essentially by the participants and the game leader.
During the training session, only the game leader manipulates the computer. No computer knowledge is required of the players. The latter can, nevertheless, consult at any time the state of the system in relation to the six areas described above.
