I tell you, I'm not into forcing religion on anyone, and I'm not really Christian, but the game looks alright. Not much different than Command & Conquer by the looks of it. It will live and die on whether it's a worthwhile game or not. http://www.leftbehindgames.com/pages/faq.htm
That special edition looks crazy (saw it while at Target). It has a book, a musical score (which is kinda funny when you buy it with the game that has the score and therefore you haven't heard the music in the game yet) and other crazy stuff.
