Devine founded Trilobyte in December 1990 with Rob Landeros. Together, they designed the original concept of the 1992 puzzle gameThe 7th Guest. Graeme was the lead programmer on the game and on its sequel The 11th Hour. The 7th Guest sold 2 million copies, and is credited (along with the game Myst) with encouraging the use of CD-ROM drives for games.
After the demise of Trilobyte in the late 1990s, Devine joined id Software in 1999[5] to work as a designer on Quake III Arena and Quake III Team Arena. At id he gained recognition in the Mac gaming community for supporting development on the platform. He also worked on the Game Boy Advance versions of Commander Keen (2001), Wolfenstein 3D, and Doom II, and was a programmer on Doom 3 until he moved to Ensemble in August 2003. Matthew J. Costello, who worked with Devine on The 7th Guest, would also help plot Doom 3 and, like 7th Guest, later novelize it. Devine then took the Lead Designer position for Halo Wars, an RTS for the Xbox 360. In February 2008 Devine was named one of the Top 100 Developers in the video game industry.[6]
In 2009, Devine was hired by Apple Inc. He was in charge of making sure that Apple's iOS devices play games well.[7][8] In December 2010, he left Apple to focus on developing games on iOS devices.[9]
