Works as a Senior Software Engineer for Autodesk. Bell was a speaker at the 2009 GameCity game festival. Bell mentioned in his speech about the impact of games: "You're reaching into the minds and the imaginary spaces of children, and you’re to an extent shaping their characters and their life stories. I’m glad [Elite] isn't Doom because I'm glad that even though we didn't really think in these terms, I think its effect on players and on people's lives is good, both in the sense of giving them good memories but also in making people think in different ways and awakening interest."
His work on Elite (1984), included programming in machine code with the assembly language. The game was based on an open-ended non-linear game model, and included revolutionary 3-D graphics, at the time. Prior to Elite, he developed Free Fall, a game set inside a coriolis space station with the player controlling an alien punching astronaut. Free Fall, was published by Acornsoft in 1983, also a game for the BBC Micro.
