Christian Media

I don’t know how to say this in a way that doesn’t sound like I’m trying to hate on people for doing what they believe in, but I feel this is something that must be said.
I found out about a “Christian” guitar video game (I don’t know that a video game has beliefs, but that’s how it’s marketed) that is very similar to Guitar Hero/Rock Band.
Reading about it, and watching some videos on YouTube, it looks like a solid product.
I guess I just find it, umm, interesting to observe the differences between how it is marketed versus how the other game is marketed.
Here is the trailer for Guitar Praise

Why am I so frustrated about this? I’m not quite sure.
