Somebody asked me what I thought next generation meant and what about the PlayStation 3 was next generation. The only next gen system I've seen is the Wii - the PS3 and the Xbox 360 feel like better versions of the last, but pretty much the same game with incremental improvement.

I think the idea of having a game based on reality is compelling right off the bat because everyone has some experience with the subject of the game.

A lot of the interesting issues and dynamics within a city occur over things such as socio-economic issues or ethnic issues. But they require a much more elaborate model of human behavior.

Also, after people play these Sim games, it tends to change their perception of the world around them, so they see their city, house or family in a slightly different way after playing.

The console games, as they come out with this new generation, will have a temporary advantage in price performance, but there are still many things you can do on a PC, more conveniently than you can do on a console machine.

Television is a very different thing from video games. It's kind of hard for me to compare.

And so from that, I've always been fascinated with the idea that complexity can come out of such simplicity.
