Seeing how quite a few of us here are both Christians and gamers, I thought to bring your attention to a book I bought today, titled "Of Games and God", by Kevin Schut.

Reading online about what people thought of this book, most say it's a fair and balanced treatment of the subject of games from an informed Christian perspective. I'll let you know what I think after I've read it ... but if you're keen now, can't hurt to check it out.
