Around late 2002, John Passfield made available some games he developed with Steve Stamatiadis back in 1999. As you'd know, John and Steve co-founded Krome Studios, currently Australia's largest game developer...
The two titles are "The Chronicles of Jaruu Tenk" and "Halloween Spirit Board". Both represent my foray into AI and living worlds and both were done completely out of love on a part time basis (ie. for a zero budget and with extremely limited resources - I did all the game coding, design and writing, while Steve Stamatiadis did all the graphics and Tony Ball did the 3D renderer). Looking back at them now I wonder what we could have done with a bigger budget, a proper schedule and a design that included actual gameplay.
They were freely available at John's website for quite a while, and have only just been put back up at www.passfieldgames.com. I highly recommend downloading them for a look if you haven't already. Be sure to give John some feedback at his Game Musings!!
