Oh man. This is such an interesting question, and one that I could talk for a long time about. I'm incredibly interested in storytelling and the social impact that stories can have, and even more interested in the possibilities that gaming as a medium opens up in that regard. Games have the opportunity to allow the player to identify with the characters in a way that books and movies can't approach. While all mediums, whether books, or movies, or paintings, or what have you, all have their own unique facets and storytelling devices, games are so radically different, they open up an entirely new creative world. I'm sure there are movies that have inspired a lot of emotion in me and, for example, have made me cry, and books certainly have -- but so many games have done the same thing, and in a way that forces me to remember each and every one of them (Life is Strange, To the Moon, and The Last of Us would be a few examples).
And certainly, games have had a huge impact on me. I remember writing in first grade that I wanted to be a "video game designer," and now, I'm majoring in compsci and minoring in graphic design because I still want to make games. I want to tell stories through games that affect people the same way these other amazing stories have affected me. I'm interested in art in general, and the way art can affect people and effect change -- and games are an incredibly versatile and impactful medium that, in my opinion, is often not utilized to its full potential.
I also like blowing s*** up and shooting dudes, too. That's also fun. See? Versatile.
