Ok. There seem to be a few misconceptions in this thread! I am a 'games developer' (coder) so here are my 2 cents.
Firstly I would be very suspicious of any course called 'game development'. There are 3 main areas of game development: design, art, and engineering. Each of which is separate and has a completely different education path. It doesn't really make sense to wrap them up into one course.
Secondly, every person in the industry I know would not recommend doing any non-traditional course. I.e. if you want to be a coder then study maths, physics, computer science or engineering. If you want to be an artist then study fine art. E.g for a coder at A level, a good selection would be maths, further maths, and physics.
So to sum up, the best route to the industry is to 1) know early on what role you want, 2) study traditional subjects which develop the skills required for that role, 3) do game projects in your own time during study to build up a portfolio.
If you do all 3 you will walk into a good job.
It is generally hardest to become an entry level designer and going the designer route has a less obvious education path and a greater emphasis on portfolio and 'interview skills'.
For all the Abertay folks, the course may be the best 'games' course but it involves only a low level of maths and the lecturers (though nice people) have next to no industry experience and none of them can code very well! I would not recommend it (I did the CGT masters there).
Any questions, just ask.
