The magazine focused exclusively on PlayStation hardware, software, and culture, covering the original PlayStation, PlayStation 2, PlayStation 3 and PlayStation Portable.

After "OPM" was discontinued in January 2007, the independent PlayStation magazine "PSM" became "" in December 2007, replacing "OPM" as the official magazine focusing on Sony game consoles.

Demo discs.
"OPM" was the first gaming magazine to include a disc that featured playable demos of PlayStation games. Beginning with issue one, each magazine came with a disc containing playable PlayStation game demos and non-playable video footage. Later, interviews, industry event coverage, and video walkthroughs of games would also be included on the discs. Beginning with issue 49 (October 2001), the magazine came with a PlayStation 2 demo disc, though for a time it would still be alternated with original PlayStation demo discs. Issues 50, 52, and 54 were the last issues to include demo discs for the original PlayStation. All of the demo discs were developed by LifeLike Productions, Inc.
"OPM" had released one PlayStation Portable demo, "Killzone Liberation". It was available only with the purchase of retail copies rather than subscription issues. The magazine was discontinued before making the assumed transition to PlayStation 3 demo discs.
