Studying technical subject improves your . Solving physical and math problems helps you to look at a problem abstractly, is very important. I’m graduating after 3 month and getting an engineer-physicist diploma (5.5 years) with an excellence. But the gain is not that I learned how a synchrotron works. I learned how to study, where to look for the information and how to solve problems. is what more experienced guys give to you. It is hard to learn yourself.
In the beginning of year I decided that I want to develop games after graduation, not to build large colliders. Well, I had some experience in gamedev, but that’s not enough to get a job. Now I work hardly on my game at evenings, after studying&working. Well, it goes slowly, because I hate 3D modeling and I don’t have a 3D modeler, so I have to “art” myself :'(. But when I deal with programming gameplay and solving math, it goes well.
If you are not educated, you are going to reach your skills saturation sooner than an educated guy. Simply because the latter thinks wider. In other words, able to solve more complex problems and give more ideas.
I think if everybody who develops games learned only gamedev and some math, there wouldn’t be such a diversity of games.
My advise: don’t quit your university by no means.
P.S. What is your university?
