I only read your pasting Meta.
As a gamer, I don't care if a game was made by Christians trying to make me more religious or whatever. I only care about how much fun I'm going to have with their game and if I have my money's worth, which is a very relative thing.
Having fun with a game, for me, includes how much I appreciate the gameplay, the grapphics, the sounds, the music, the colors, the animations, the voice work, the story, etc. It's a combination of things. Like ingredients in food, some taste good, others are bad but the important thing is how it tastes once finished.
Are games art? I really believe so but only as much as movies or even television scripted shows are art. And their main function is to make money, not make you cry with some artsy message about the fall of society and love or something.
In any case, I don't think anyone can disagree with the fact that, at the very least, games contain art.
