Pinball Construction Set created a new genre of video games—the "builder" or "construction set" class of games. With PCS, users can construct their own virtual pinball machine, by dropping controls onto a table. Controls included bumpers, flippers, spinners and other standard pinball paraphernalia. Attributes such as gravity and the physics model could also be modified. Users could save their creations and develop custom artwork to go along with them. Tables could be saved on floppy disks and freely traded; Pinball Construction Set was not needed to play the tables.
