You can't fairly judge what a person (or a group of people) does based on what their religion is. I actually became a member of that website nearly 3 years ago now, and I must say that not once in the several times of activity that I've "played" there have I seen any kind of religious indications at all. I checked it out in pretty great length just out of curiosity, too. So please don't jump to nasty premature conclusions. I'm sure you could probably pick it apart and find something or other to back up that opinion. For that matter you can turn anything around when it's convenient. I don't want to discount something you may have seen as evidence, but I just haven't seen it and I look at that site from a totally neutral standpoint -- the average end-user. I know plenty of other adults who are regulars who enjoy it for what it is... cheap, simple, fun & clean ("kid-safe" even) entertainment. If you have some facts that might sway that other than just the basis of what their religion is, bring it on, I would, sincerely, love to know.
And I just have to mention in reply to the last post and what many people seem to take issue with that it's incredibly easy to become "addicted" to just about anything on the internet... from forum posting, to email reading, to chatting with buddies on chat services, to playing games on websites. Not trying to critisize at all, as I have been just as guilty of this in the past, but have learned from my experiences. I just know of too many people who think things like this in general are "bad" or "evil" but the real problem is the human factor and the lack of self control, or worse - the desire for such selfishness.
Humans are so prone to never take the blame for things, but to constantly seek for somewhere else to place the blame. There's nothing to be worried about here except for ourselves. Keep a little self control, and you'll be just fine.
Anyway, back to my point. They're no cult, they're just a business who has done well for themselves. I certainly can't blame them for that.
