This was apparently sent out recently by the CEO of Left Behind Games to be posted by the game's supporters on critical blogs:

This post is provided by Troy Lyndon, the CEO of Left Behind Games.
FOCUS ON THE FAMILY endorses our game. Read below to find out why!
Our game DOES NOT encourage killing.
Our game is NOT anti-semitic.
Our game is NOT anti-muslim or anti-islamic.
It is anti-EVIL! The ultimate bad-guy is the Antichrist who wants to eliminate all faiths and all religions, except his and he is deceiving the entire world.
Our game does NOT teach the pre-tribulation theology of the book series, except that this worldview is utilized as a FICTIONAL backdrop of the game.
In the past several days, numerous people have been and continue to spread misinformation about the game.
Our game is the first game ever to encourage the use of PRAYER and WORSHIP as the most effective means to resolve conflict.
Physical warfare is discouraged as the LEAST EFFECTIVE means for resolving conflict…and a gamer loses points for using a gun.
This is the world’s first high-quality inspirational game which intends to model positive behavior by discouraging physical warfare.
Please play the game for yourself and help us to get out the TRUTH.
In an industry which creates so much gratuitous violence and gore, LEFT BEHIND: Eternal Forces presents a healthy alternative. We need your help to get the word out!
PLAY THE GAME and find out for yourself that this game is about the battle of good versus evil.
Here are a few things said by others:
- The Anti-Defamation League, although they speak out against the book theology, says “Conversion to Christianity in the game is not depicted as forcible in nature, and violence is not rewarded in the game.”
- AOL says it is a “Positive Moral Message”
- Focus on the Family says “Finally! A game Mom and Dad can play with Junior”
- Concerned Women for America says “A game we can wholeheartedly recommend!”
- Wired Magazine “Few are as ambitious and polished as this PC title.”
- ArsTechnica.com “This is a game that Christian parents can buy their kids, and one that Christian kids can play themselves without any guilt about "questionable content."”
- Women of Faith says “In an industry that is full of destruction with no hope, the LEFT BEHIND game offers hope and a positive message”
- Clint Thomas from Chaos Theory says “For years we’ve been telling kids what to run from and not what to run to, until now!”

Download the game's DEMO and decide for yourself. Just as I was thinking the game wasn't impressive on any level, and had built a small army of Christian soldiers, the demo crashed on me. Go figure. I haven't played SIMs, but my impression is that it's along the same style.
