I'm a game play designer specializing in systems and combat design. I love finding out exactly how many milliseconds is the RIGHT number of milliseconds and discussing statistics (You can never have enough data points).
I've been testing, designing and developing games for a few years now and nothing else I've done has quite the same sense of collaborative discovery. There are so many different ways to make so many different games "fun." That sense of boundless possibility never gets old.
I'm a huge nerd and when I'm not busy arguing with my girlfriend about whether Data can download himself into a new body and still be the same person, I love to make games.
