conceived as a larger, non-linear open platform game for the GameCube. However, a simpler design and simpler concept were adopted due to the Microsoft buyout and increasing time constraints. After Microsoft's purchase of Rare, the studio re-affirmed their "simple design" of the game so that players would be able to easily adapt and devote less commitment to it. In a retrospective interview, Mayles stated that the change from GameCube to Xbox was difficult and required a lot of changes as Grabbed by the Ghoulies was "an original game that started life as a Nintendo product". According to Mayles, Grabbed by the Ghoulies was not inspired by Rare's similar-themed Atic Atac. The cel-shaded art style and design of the characters in Grabbed by the Ghoulies were inspired by Hanna-Barbera cartoons, and the various character personalities were based both on historical figures and people from Mayles' childhood. Antagonist Baron von Ghoul was "a mix" of the Red Baron and British aristocracy, whereas supportive characters, such as Ma Soupswill, were loosely based on staff from a school. Mayles considered the conversion of the game to the Xbox to be one of the hardest challenges during development, as Rare had less than a year to finish the game once it was converted. The game was revealed at E3 2003, with a playable demo being a mostly complete version of the game, albeit with a few levels missing. Grabbed by the Ghoulies was released in North America on 21 October 2003, in Europe on 21 November and in Japan on 29 April 2004, becoming Rare's first game to be released under Microsoft. It was later re-released as an Xbox Originals game for the Xbox 360 on 16 February 2009, later being removed from the store on 16 June 2015, before the Rare Replay compilation game which included it was released on 4 August 2015. The game was remastered to run natively on the Xbox One, increasing its resolution and framerate relative to the original Xbox release. Grabbed by the Ghoulies was one of the first original Xbox games to be compatible with Xbox One via backwards compatibility. Reception The game was met with mixed reviews from critics upon release. It holds an average score of 66/100 at Metacritic, based on an aggregate of 42 reviews. The graphics and animation were praised by critics. Kevin Gifford of 1UP stated that the cel-shaded graphics were "perfect" for
