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
Also, FF4 Advance (American version) has a nasty bug during battle where characters go out of order, get their turns skipped, etc. The slowdown can get pretty grating. I think you can change the battle settings so you don't see the ATB bar..
