It'd be more interesting to compare religious/nonreligious/etc with the brand loyalty gamers hold. Some are super loyal to their brand of choice (the religious/devout) and would never play on any platform than the one they prefer, the multi-console owners (polytheists of the gaming world), the non gamer (atheist), the casual (agnostic).
Just a random thing I thought of. But I would like to see a thread that discusses it like this someday XD
