Doug Church: Object Systems, Immersive Sims

Here's a presentation by Doug Church (Looking Glass, Valve) from about 2003, about designing Object Systems for games.  

I've reformatted it a bit to make it easier to read, and included it here because I love the Thief games, and thought others might be interested in it too.

It is written (I assume) with an eye towards immersive sims, and other games where you want rich interactions and emergent gameplay possibilities.

Here's the Google Slides, and here's a PDF.

I wish I had an audio recording of the presentation, but I don't think any such thing exists.

Enjoy!


PS: Here's a little preview of a few of the slides from the presentation...
