This issue of GamesMaster Presents is split half-and-half between the Mario and Sonic franchises. The Mario section starts on the front cover, while the Sonic section starts on the back cover and is printed upside-down. The two parts meet in the center of the magazine for a feature about the franchises' shared rivalry and history.

This collection includes all 285 issues from the main run of Nintendo Power, as well as several supplemental issues. Because of the large number of special and supplemental issues released for Nintendo Power, missing special issues are not listed in the notes for this record.
