Excellent game(Very addictive game), but borderline um how to I put it ....oh "questionable religious content". By questionable it is really not that questionable......it is borderline..... 

Given I am not a religious person I do not care as a reflection of me, but I think it is better if any game Nintendo passes up for being too mature, it might as well be this one.

Is it anti or pro?
