My first question would be “does their college run a games course?”, its also sadly true that many people in education don’t recognise how transferable a games education is, and how broad the field (and the skills within it) are.
It might also depend on what they believe a games course to be, they might well be behind the times and think that there are still only 1 year introductory courses out there.
Do you know anyone else who would have been interviewed for another specialist area? If so what were they told? If you know anyone who said they wanted to go into web design and they were recommended to do so, I’d put the response down to bias, either as a result of ignorance, or actual disdain towards the games industry.
