Croshaw became known in the Adventure Game Studio community for the "Rob Blanc" trilogy. He then created another AGS game, "The Trials of Odysseus Kent", which was released on 30 September 2002. "The Trials of Odysseus Kent" was mentioned by "PC Plus" magazine as "AGS Showcase" in the November 2003 issue. He also helped found the collaborative "Reality-on-the-Norm" series by creating the first game, "Lunchtime of the Damned". The series has gone on to have over 50 episodes since. In 2003, Croshaw created a total conversion mod for "Duke Nukem 3D: Atomic Edition" called "Age of Evil". Some of his later works experimented with the AGS engine to produce games in other genres than the point-and-click adventure games that AGS was designed for, such as "Adventures in the Galaxy of Fantabulous Wonderment", and the "1213" series.
