In cases like these I have always been on the wall. I love gaming, even though I rarely play anymore. But my second job involves indie work with game companies, so yes I have a deep connection to gaming. But in cases like these it always comes down to the minds involved. Some minds are strong and have a good grasp on reality, while some are very easily manipulated by basic imagery and story telling. Sometimes real life involvement isn't the only element of environment that can affect a mind/growing mind. Again I'm more or less on the wall.
