Kim Swift quotes:

The drawings in 'Portal' were actually me scribbling that stuff... I had a funny moment when I realized that someone gotten 'The cake is a lie' tattooed on themselves. It was really interesting to see my handwriting tattooed on another human being. That... that's odd.

One of the things I loved about working on 'Portal' was that we'd get emails from people saying, 'I love to play first-person shooters but my girlfriend won't play them with me. But I got her to play 'Portal' and she had a blast.'

I think if a person plays 'Quantum Conundrum' and they walk away feeling really intelligent and skilled, that's what I want. That's my only goal.

I think the downloadable scene in general is really, really interesting for developers because it's low-risk. It doesn't require as much money as a triple-A title. And it's a great proving ground for new IPs, new concepts, new ideas - things that I think I, as a developer, find really attractive.

I'd been at Valve since I got out of college. I felt like I kind of grew up there, and I wanted to see what else was out in the world. One of the owners of Airtight Games is a friend of mine, and he asked if I would run a team there. It just sounded like a great opportunity.

Being young is an advantage. You've grown up with games as the dominant entertainment. You have a lot of experience of video games. So what do you want to see that's not been done? Innovation is really low cost for you. You can afford to take risks and fail to execute new ideas.

Games can be art, and they can be significant and all the glorified things that we want them to be. But if you ask a kid if their toys are important, they'll say 'yes,' and 'Please don't take them away.'

I love humorous games. I love to laugh, and I think it's a really great way to attract players."
