Hey! For once, I'm not arguing with BlKnight!
I've been arguing the same point with myself for a while now (I don't have piety yet so it doesn't matter). I do have conscience concerns with "praying" to a god, even if both the god and the prayer are acknowledged to be fictional... something I'm gonna work out for myself. Probably if I get piety I'll just decide in favor of using it, though. I'm weak that way.
EDIT: Koni, killing on a computer game and praying on a computer game aren't quite the same thing. Not to some of us, anyway. But it's interesting that if my character never prays, I'm effectively rping an atheist/agnostic, and is that any more compatible with Christianity than rping idolatry? (Probably, but, well...... whatever).
