I was working on my doctorate in neuroscience, actually. And, uh, at the time, I was, uh, spending a lot of time in the lab and running a lot of experience late -- experiments late at night. And I was -- I was really hooked on Quake. And, uh, I had just never been hooked on a videogame like that. You know, I've always loved videogames but, you know, never been a junkie like that. And I was -- I was really having fun dabbling in level design and just making Quake levels in my spare time. And, in fact, the -- after just making a couple of levels, uh, one of them actually became really, really popular in the -- you know, in the hobbyist level design community. And so, you know, a few weeks later, I actually started getting emails from game companies, saying, "Do you want to come make games?" And so I didn't know anything about game design. I didn't -- I had no art skills and, uh, no engineering skills. And, uh, I really just lucked out. I think I was in the right place at the right time. And, uh, clearly there was -- um, I had some, some kind of skill, I guess, you know, some kind of talent for doing that. And, um, so I came in, you know, built levels for a long time, and, and kept honing my design skill, and took it larger from level design to game design and then to creative direction.
