that i have some brilliant plan or something
Well, I am not asking you to do something that is impossible. It's like this: You might be a student who does not think about the future very much, or you might be a student who feels very passionate about something and therefore does a lot of reading about the subjects of interest.
If you read insatiably as the result of caring deeply about something, then you will automatically have a plan that includes several goals. You will be hurrying to achieve those goals that come as a result of the reading you have been doing. It's all about the reading.
So far, all you did was say you want to get involved with creating video games, but why? Could it be because you mistakenly think making games will be as fun as playing them? Or is it because of something that is truly important to you as an artist? Give some sentences that will make me believe that you really know what you want to do.
Otherwise, I will favor the applicants who are acting on a philosophy of life, a real commitment to something you think is truly important. If you represent an important concept, you will BE important, and the reader will favor you.
