Prior to Zero Punctuation, Croshaw primarily authored content for his blog, Fullyramblomatic, and would occasionally review video games, often with an emphasis on humor and criticism.

[1] In July 2007, Croshaw uploaded two game reviews in video format to YouTube in the same style that would eventually be used for Zero Punctuation: one of the demo of The Darkness for the PlayStation 3, and the other of Fable: The Lost Chapters for the PC.

These include the video game industry crash of 1983, and the controversial Hot Coffee mod for Grand Theft Auto: San Andreas.

These articles were originally published every Tuesday and often supplemented the previous week's review by discussing a certain topic or trend exhibited by that game.

[14][15][16] In Zero Punctuation, Croshaw usually reviews a game in a highly critical manner using rapid-fire speech delivery accompanied by minimalistic cartoon imagery and animation on a distinctive yellow background, which illustrates what is being said or provides an ironic counterpoint to it.

His reviews are intended to be humorous with constant usage of puns, analogies, metaphors, and dark humour accompanied by frequent use of profanity.

Video games, developers, countries, and other entities are often anthropomorphized as box arts, logos, or flags, respectively, with arms and legs.

Prior to mid-2008, Zero Punctuation featured commercial songs at the beginning and end of each episode, which were usually related to the context of, or at odds with the game in question, such as the Ramones' "I Wanna Be Sedated" and Eric Johnson's "Cliffs of Dover" at the beginning and end, respectively, of his review of Guitar Hero III: Legends of Rock.

[4][24] He tends to disdain certain tropes and conventions in video games he feels have been overused, such as quick time events, highly common uses of motion controls, cover-based shooting, crafting systems,[25][26][27][28][29][30] and an unbalanced emphasis on graphics over story or gameplay.

[38][39] He also disapproves of game franchises that release sequels in rapid succession, such as Final Fantasy, Assassin's Creed, and Call of Duty.

[44] Croshaw cites the work of British television critic and PC Zone journalist Charlie Brooker as the "main inspiration" for his own reviewing style, as well as the writings of Douglas Adams, Sean "Seanbaby" Riley, Victor Lewis-Smith, and Old Man Murray's Chet Faliszek and Erik Wolpaw.

[50] In a 2018 review of Kingdom Come: Deliverance, Croshaw explained that he regretted calling the community "PC master race" instead of "dick-slurp all-stars," citing a continuation of the behavior that originally prompted the term.

Radical Entertainment and Sucker Punch – the respective developers – unexpectedly complied with the challenge, prompting Croshaw to declare InFamous the winner after judging the quality of the images.
