Is is useful to get a degree in "Advertising"?

[Harmen]

Hey I am not quite sure what I am going to study in the future. At first I thought something with game design but then I thought this might something I will regret in the future. Then I thought maybe advertisement would be nice. I really love to do stuff on the computer such as editing movies, or some work with a CAD program. My school subjects are ICT, media studies, Design and German (english A levels) and I think these subjects are use full in this area, of course business studies would help as well, but I was not good at it. Do you have any advices, tips or experiences to share, this would be cool
Please note that I am german, therefore my english might be a bit weak here and there
