A modular infrastructure, for an interactive computer program comprising a computer generated environment, comprising an instrument module, a seat and a display. The instrument module replicates a first and a third portion of a cockpit from a simulated vehicle. The instrument module comprises a tangible instrument for a user to interact within the computer generated environment and a shared tangible instrument, replicating the third portion accessible to a real co-user in a second infrastructure, which replicates a second and the third portion of the cockpit. Images from the computer generated environment and of a virtualized participant representing the real co-user are displayed. A display position relative to an instrument position of the third portion and relative to a seat position is customizable to support different configurations of the interactive computer program. A method for providing the interactive computer program in the modular infrastructure and the second infrastructure.
