If you're okay with sexual innuendo, even though some kids may not "get it," then I suppose it would be okay.
I would not allow children to play this game because of the sexualized comments when you post needing a particular item or allowing others to collect a bonus. Examples would be a girl holding two melons in a certain area, saying, "Look at Kelly's melons." Or a man holding a log a certain way in a certain area with a reference to 'hard wood' or 'how long is it'? In fact, I stopped playing becase I was tired of it and found it very inappropriate.
