Okane ga Aru Kono 12-gatu ni PS4 wo Katte Shiawasena Fuyu wo Sugosu Tame no 10 no Riyuu (Vol.652 supplement) (December 28, 2017)

supplement included with Dengeki PlayStation Vol.652. The title translates roughly to: "10 reasons to spend a happy winter buying a PS4 if you've got the money." Furthermore, it claims that the target of the book is you, the salaryman, perhaps acting as evidence that Dengeki PlayStation's readership generally skewed older than that of mags like Famitsu.
