At least they don't have a follow the niche hardcore gamer herd mentality. :)
They don't need to follow the hardcore niche. They do need well written reviews, and a site that doesn't look like it was thrown together in 30 minutes. Not to mention the site isn't very useful if it has no information on games like MGS4, Halo 3, Call of Duty 4, Uncharted, Grand Theft Auto 4, Ratchet & Clank, etc. These are the games parents would need information on, not Cars and The Bible Game. Although apparently M rated games are "porn" and "morally corrupt".
Also, why is there a family friendly rating when it seems every rating is determined by it. For DQVIII you say "The graphics are some of the most impressive to grace the PS2" but it receives a 70%. I can only assume this is due to many images "not promot[ing] a positive view toward the Christian faith".
Anyways, the reviews are poorly written (even by video game journalism standards), the scores are relatively worthless in terms of the quality of the game, and the site is just painful to navigate. Maybe I am missing the point, and you merely wish to differentiate between the evil heathen games and the righteous Christian games. However if this is true, it seems that listing the "morally corrupt" content, and giving it a letter rating from Angelic to Flagitious would be more effective.
I finally remembered this other similar site. http://www.whattheyplay.com Perhaps it doesn't fit the mantra of Mature games are evil, but it is infinitely more useful to parents. Why I have wasted so much time on this is a mystery.
