The One was a U.K. published magazine that covered various mostly 16-bit systems over the course of its life. In late 1989, it was covering the Amiga, Atari ST, and PC (DOS). The December 1989 issue includes:
Departments
Play Guide - A guide to Activision's Fighter Bomber, a combat flight simulator. This game was known as Strike Aces in the U.S. While I don't see a mention as to what platform this review is for, this game was released on the Atari ST, DOS, Amstrad CPC, Amiga, ZX Spectrum, and Commodore 64.
Feature - A preview of the new Ghostbusters II game. While the graphics were nice the game was sadly not as much fun as the original game.
Demos - A look at various demos including Interphase, Stay, Magnetic Beats, Ghostbusters II, DTack, and Moonwalker for the Amiga and Batman and UFO for the Atari ST.
Graphics - A tutorial for how to create fancy looking text on the Amiga and Atari ST.
Arcades - A look at new and upcoming arcade releases including Chase HQ II from Taito, Midnight Resistance from Data East, and X-Multiply from Irem.
Feature - A look at the current state and future of Artificial Intelligence. It's interesting to look back on how AI was viewed 35 years ago.
