The general consensus seems to be that specialist courses in Videogame Design aren’t worth it. Depending on what you want to do, you are better off doing something like Computer Sciences, or Art, or something like that, i.e. something that has a direct bearing on what you want to do in the industry (and, above all, what you ENJOY doing). I only ever hear of people in the industry getting their jobs based on things they have built with game engines and mods. If you can point to the stuff you have made, rather than the completion of a course, that is what will get you an interview.
I’m not in the game industry, but I am in IT, and when I interview people, I look at experience and Github accounts. I never look at their degree. (Mine’s in English Literature, for example 
).
And, yes, courses can be different, because they can teach from different syllabuses.
