Gottlieb made some very nice games. Had quite a few stinkers as well, mostly due to a big lack of refinement in the software department.
I own a Black Hole, Haunted House, TX-Sector, Night Moves and Street Fighter II and I like them all. TX and Black Hole are definately my favorites of the bunch. I also own a Hot Fire Birds, a machine by German brand NSM. It has a playfield designed and produced by Premier/Gottlieb inside it. My brother owns an Arena and a Surf 'n' Safari, which we enjoy immensely with a few beers on the side.
