There is a substantial difference in game design between what you study and what you then work on.
When you study you learn the basic language and how to get from an idea to a game. Most often it is a reduced version of the game itself. When you study you have the largest freedom to create without thinking too much about who sells the game. The ability to create will be one of the fundamental ones.
When you’re working, your primary focus is the team in charge of selling the game to the people out there. You will need a very different set of skills. You will need to support your work with ideas that have worked in other games. The ability to analyze becomes one of the fundamental skills.
If you are a student, take advantage of the beautiful moments of creative freedom. But never forget to play many games. Because playing will build you a library of ideas and mechanics and will be your basis for real work.
PRO TIP: play more games from the companies in your geographical areas. Those will be the first you will apply to.
