It never ceases to amaze me how people become celebrities in this industry, just because they work on a high profile project, or for a high profile company. A project with good PR can both make the project a success, but ensure the success of the people working on it. Often the level of their skill is not a question. This train of thought can be tracked to people who work for iD software. I know who Robert Duffy is, I know what he does, only because he works for iD. I don't like most of the projects he has worked on, yet I still would see him as a big figure in the Games Industry. GameSpy have a chat with mister Duffy today that tackles all manner of subjects, none of which touching what Duffy or iD are up to these days, or the whole Paul Steed issue.
Robert Duffy got a job in iD software mainly as a result of the QERadiant level editor he made for Quake 2. Everyone I know who has even a passing interest in level editing has no time for QERadiant, due mainly for the massive learning curve involved in doing anything with it, Duffy says, "It gets knocked around a bit because of the learning curve, but it quite simply provides the most functionality available for level design work".
A large part of the rest of the interview is what games Duffy plays, and what Car he drives, but none the less it is an insight into a high profile figure in the industry.
