This. In a previous life we were asked to install a motion platform for a vehicle simulator. Our customers had a small hangar-like building with a free corner, and a research budget that could easily afford the hardware required. But the installation required floor safety markings, physical barriers and interlocks so that bystanders couldn't get whacked and integration with the building fire alarm system so that in an emergency the sim would park in a safe position so that the trainees could exit. The latter required software development as well.
