In the information age, the barriers [to entry into programming] just aren't there. The barriers are self imposed. If you want to set off and go develop some grand new thing, you don't need millions of dollars of capitalization. You need enough pizza and Diet Coke to stick in your refrigerator, a cheap PC to work on, and the dedication to go through with it. We slept on floors. We waded across rivers.

Focus is a matter of deciding what things you're not going to do.

It is difficult to make good scalable use of a CPU like you can of a graphics card. You certainly don't want 'better or worse' physics or AI in your game

The Xbox 360 is the first console that I've ever worked with that actually has development tools that are better for games than what we've had on PC.

If you aren't sure which way to do something, do it both ways and see which works better.

Low-level programming is good for the programmer's soul.

Programming in the abstract sense is what I really enjoy. I enjoy lots of different areas of it... I'm taking a great deal of enjoyment writing device drivers for Linux. I could also be having a good time writing a database manager or something because there are always interesting problems.
