During my junior year at Wesleyan, I took a videogame development class from Christopher Weaver, founder of Bethesda Softworks.
The class aimed to mimick real-world software development, so all students spent the semester building an education STEM game for elementary school kids end-to-end. I pitched an idea and formed a team of five (an illustrator, three programmers, one of which did sound design, and myself on production and UI). We developed a game in which players "built" famous inventions and learned how they work.
