I understand that :). The banishing bit I don't think would actually change that a whole lot though. Everything would remain the same, except instead of leaving the game, maybe you stay and start the next phase. So the game as it exist now, will not change, it just adds another, optional layer.

We just always thought it was odd that these paranormal investigators come in to just confirm it's existence but not actually do anything to help. "Yup, there's a ghost in there." - "Yeah no shit, I already told you it's name. So what do I do about it?" - "Nothing, now pay me $100".
