I studied Game Design (in Brazil to take that course you must also learn product design in general), and I am a HORRIBLE artist. And I get depressed every time someone call the artist on my team the designer. No damnit, I am the designer (and the coder), I design stuff, I don't make the art of the stuff, I design how they work, how they should behave, how the user interacts, and I code that, and the artist make it pretty. On my own country this is even worse, designer has no clear direct translation, AND sounds analogue to "desenho" ("desenho" in portuguese means "drawing" in english), so when I say I am a designer lots of people think I do "desenhos" (drawings), what I do now is call my profession in portuguese "projetista" (in english it would mean something like "guy that do projects") so that is clear to people what I do.
