Abstract
A system for limiting the number of different video game machines on which a cartridge may be played so as to effectively inhibit the conduct of a cartridge rental business. Every machine has a serial number. Every cartridge records the serial number of any machine on which it is played, up to a maximum number (e.g., ten) of such serial numbers. A machine will not play an inserted cartridge if its serial number is not recorded in the cartridge and if there is no room left to record it.
