... now one third of the mag is centred around a title that was released a few months ago. ...

Actually Stern's KISS is only about 30 pages or so. Bally's KISS is discussed as part of the Jim Patla and Kevin o'Connor interviews, but these interviews cover their years at Bally, not just one game. The third KISS game discussed is Zidware's KISS Pinball Maximus, which was just a prototype that may have urged another company to pursue that license. So about 1/3 of the magazine can be seen as related to KISS themed pinball machines, but that are 3 titles.
