Craig Detweiler, director of the Center for Entertainment, Media, and Culture at Pepperdine University, has edited a new collection of essays that explore the theological implications of popular video games like Halo 3 and Resident Evil.
As he explains in the introduction to the book, Halos and Avatars:

With the arrival of James Cameron’s all-digital Avatar, more people have begun wondering how to navigate virtual worlds and video games. … Those searching for a cautionary tale will be disappointed by this book. Halos and Avatars aims to demystify the gaming universe and dignify the passions of the most active gamers. We believe in the theological possibilities contained within even the most debased pop culture.
