Some cynical people think that every activity must revolve around the mighty dollar, and that anyone saying otherwise is just attempting to delude the public. I will probably never be able to convice them that that isn't always the case, but I do have the satisfaction of knowing that I live in a less dingy world than they do.

It's nice to have a game that sells a million copies.

One of the big lessons of a big project is you don't want people that aren't really programmers programming, you'll suffer for it!

If you're willing to restrict the flexibility of your approach, you can almost always do something better

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 situation is so much better for programmers today - a cheap used PC, a linux CD, and an internet account, and you have all the tools necessary to work your way to any level of programming skill you want to shoot for.

Because of the nature of Moore's law, anything that an extremely clever graphics programmer can do at one point can be replicated by a merely competent programmer some number of years later.
