I remember the IPDB note that was on the Gottlieb "street level" pin series, as follows:
A "Street level" game, which were an experiment by Gottlieb towards designing a simplier, single level (no ramps), slightly smaller and cheaper game. They did not sell very well, and only six models (Premier's 1990 'Silver Slugger', Premier's 1990 'Vegas', Premier's 1990 'Deadly Weapon', Premier's 1990 'Title Fight', Premier's 1991 'Car Hop' and Premier's 1991 'Hoops') were made.
The "slightly smaller" aspect confuses me. In terms of overall dimensions, I think it is clearly untrue. Silver Slugger, Title Fight, and Car Hop (H: 77", W: 27", D: 52", Weight: 260 lb.) have the same dimensions as Lights...Camera...Action (the first System 3 and only Sys3 to come before the "street level" line-up). Hoops is only 75" in height (the only dimension different), but that matches Cactus Jacks and Class of 1812 (two System 3 games just after the "street level" series ended; Cactus Jacks is the same weight but Class of 1812 does weigh more).
Vegas and Deadly Weapon are 26" wide (otherwise their dimensions match Silver Slugger, Title Fight, and Car Hop). So, are these the only ones "slightly smaller" than Gottlieb's full-featured pins (I didn't research to see if 26" was otherwise common or not)? Was it something else (less actual playable space on the playfield and/or the playfield being smaller despite the cabinet size)? Or is the IPDB statement wrong (as a majority of these games have cabinet dimensions on par with the full featured titles Gottlieb released around the same time period)?
