After two weeks of working on a project, you know whether it will work or not.

I'm a great coder. But I am not pushing that so much anymore because there are thousands of great coders.

The program should know if someone is at the keyboard or joystick or if it is just sitting there idle. It should know if someone is proficient in its use or a novice.

I started on an Apple II, which I had bought at the very end of 1978 for half of my annual income. I made $4,500 a year, and I spent half of it on the computer.

I know when something is kind of half-baked.

Video games are engineered now, but the step I am trying to take, no one can engineer.

It always helps to be a good programmer. It is important to like computers and to be able to think of things people would want to do with their computers.
