Looking for an explanation on the "gameplay designer" subcategory and how it differs from "system designer"
I've heard that the game industry is made up of specialists, not generalists, so you have to focus on a particular discipline that you wanna work on in games (programming, design, art, sound, etc). And then I've heard that even within disciplines, there are subcategories you should focus on.
I know that the general discipline that I enjoy most and want to work in is design. As for the subcategory, I have narrowed by focus to either being a "gameplay designer" or "systems designer".
In my own games, I love working out what the games mechanics will be, how they interact with each other, and how that all combines to affect the player experience. But I am kinda confused on the difference between being a gameplay and systems designer. If games are interactive systems, wouldn't all system designers be gameplay designers?
I am asking because I am an incoming freshman at one of the best game design schools (USC) and I want to go into school with a purpose and direction to give me the best shot at getting a job in this difficult industry. I know that a degree is NOT a silver bullet in game design, so this is why I am asking. I want to decide what specific things I want out of this degree so I can make the best use of it.
