The format of reviews in this feature were almost identical in every issue. The start of the article would show the "key", indicating what the abbreviations of each Sega console was and what exactly each percentage rating meant (from "Mega City!" down to "Yawnsville"). Each game would be accompanied by the game's title, the console, type of game and number of players it accomodates. After the review would come the reviewer's name (or initials) and the "Fast Fax". This would contain individual scores for graphics, sound and playability. As well as this, the reviewer included the game's Raves (positive aspects) and Graves (negatives). Later editions would feature "spike ball" graphics with either their thumb up or down. Finally, the review would receive a score to fit in with STC's rating system.
Early editions of Review Zone spanned an average of four pages, with individual reviews crossing pages to make a lively feature. Towards the end of the Mega Drive's run, when the Saturn was the only competing Sega system, the Review Zone began to wind up with fewer games to feature.
Sonic the Comic Online reintroduced the Review Zone, although largely just featuring one game every issue. This game would almost always be the most recent Sonic game to be released and the format was almost exactly the same as the print edition's version. Stuart Gipp became the comic's Review Hume, but would eventually be replaced by Iain Stewart. Although almost all reviews are provided by Stewart, occasional ones are produced by Drew Middlemas, Shadic, Seumidh MacDonald and others.
As of Issue 257, reviews no longer contain a score (apart from the Sonic the Comic 'game' that broke the rating scale). In Issue 260, a film was reviewed for the first time, namely Wreck-it Ralph, a film that contains cameos from the video game versions of Sonic the Hedgehog and Doctor Robotnik.
"*" - This game did not have a credited reviewer, so has been assigned one from the reviewer's scoring conventions.
"**" - These may have alternatively been written by Gibbon, as there were no individual credits.
"***" - Clack gave this no official score, but stated he would award it a "mid-sixties" score had he done so.
