Any RPI system can run any game or experience from other software suppliers. Windows personal computer, Unix and hybrid systems are now available. The modular systems can be configured in size from entire facilities layouts to single pods in existing amusement centres. The rides can network worldwide via the ImagiNET telecommunications system.
