Yes I have a Shipmates, Dodge City and Williams Teachers Pet that all have similar carryover features. For the Gottlieb games it really makes multiplayer games a lot more fun because you can steal each other's points and extra balls. There's also the enticement to start another game to collect points or extra balls as mentioned above. This is probably not the greatest thing for tournament games especially for qualifying. On the other hand a couple of jumpers could disable this feature if needed.
