Gaming as a hobby is the worst state, because it means there's no possibility for it to be taken as a serious art form. I can't wait until people stop thinking of games as toys and actually start seeing their deeper, more important impact on society.
I understand some games whether it be a shooter like specops or games like Deus Ex and Fallout have some sort my feels moment or look on society, conspiracy, message, etc. But uh, I wouldn't go far to say that is there purpose.
I don't play Mario to feel bad about stepping on turtles or decode it as a message to save the turtles.
Is there are time and place where story, gameplay, and hidden meaning can blend, I think so. However I think you are taking a bit far with that statement. Like not every game can be Hideo Kojima or Metal Gear Solid.
