Based on a suggestion made by company president Masaya Nakamura, its content relates to Namco video games and progressed to crafts, developer interviews, fan mail, and two manga series illustrated by Hiroshi Fuji.

[3] NG stands for "Namco Games",[4] and was published quarterly in its early years and distributed primarily at Namco-operated video arcades free of charge.

[1] Later content includes fan letters, developer interviews, papercraft models, and drawing workshops hosted by sprite artist Hiroshi "Mr. Dotman" Ono.

The switch from quarterly to bimonthly resulted in a reset in the issue number on the front cover, a page size increase from A5 to B4, and a small fee.

[4] With little income being generated from the magazine, Namco chose to retire NG on April 4, 1993 Its final issue features a congratulatory letter from the writing staff and other designers within the company.

Ranbu Yoshida, a writer for Famitsu, described the magazine's content as "really rich in variety" with plenty of interesting, provocative material.

Each Namco Generations game came with a free digital newsletter that provided information on current and upcoming projects,[10] a move believed to have been inspired by NG.
