He is best known for his video game review series Zero Punctuation, which he produced for The Escapist from 2007 to 2023, and its spiritual successor Fully Ramblomatic, which he releases through Second Wind.

[12][13] Reviews are roughly five minutes in length,[3][14] and contained no numerical rating or score,[7] as Croshaw called them "fucking nonsense when you're criticizing from a subjective artistic standpoint.

[16][17] He also wrote a selection of interactive fiction games through Z-Code, including Offensive Probing, Arthur Yahtzee: The Curse of Hell's Cheesecake, The Sorceror's Appraisal, and the Countdown trilogy tied to his Chzo Mythos.

[18][19] Croshaw then developed many freeware games[7] in Adventure Game Studio from 2000 to 2007, including the Rob Blanc trilogy,[20] Lunchtime of the Damned (the inaugural episode of Reality-On-The-Norm),[21][22] The Trials of Odysseus Kent,[23][verification needed][24] the four part Chzo Mythos,[25][26][27][28][29] Adventures In The Galaxy Of Fantabulous Wonderment,[30] the 1213 series,[31][32] and Trilby: The Art of Theft.

[39] Builds of the Chzo Mythos and other games were released in 2010 for Linux on icculus.org,[40] later updated in 2015 to the now open source AGS runtime.

[41] In April 2012,[42] Croshaw released the Cave Story inspired Poacher,[43][44] developed in GameMaker Studio,[44] which he would use to make all his subsequent games.

[‡ 5] In a 2014 Vice interview, Croshaw disclosed that he had been asked to pitch a script for the then-in-development Duke Nukem Forever by a producer.

[14] Croshaw had earlier in 2003 made a horror-themed total conversion mod for the original Duke Nukem 3D called Age of Evil.

[61][62] In the 2000s Croshaw created a number of webcomics, namely Chris and Trilby, Cowboy Comics!, The Adventures of Angular Mike, and Yahtzee Takes On The World!, which ran from December 20, 2000, to September 22, 2002.

[65][66] Tor.com's Chris Greenland stated that the book "isn't going to bowl anyone over," while adding that "Croshaw undoubtedly has a strong, unique voice and I would hate to see that limited to only critiques.

[68] The Times Herald-Record's Jim Higgins described the story as "a talky tale of political intrigue that could be straight out of Isaac Asimov's Foundation series, with a snappy twist at the end that O. Henry might appreciate.

[71] In April 2024, the final book in the series Will Leave the Galaxy for Good was published on Audible, with print and ebook versions to follow.
