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
I don't remember where I saw it (maybe here? but I checked and didn't see it), but the first episode of Back To The Future (the new series of adventure games, not the movies) is available for free on the PSN Store this month.
