I see no problem with playing these games. The G-man offers a few practical tips in the previous post.
For those who follow the "why would you fantisize about a sin" line of arguement (as ADKing does), I would say that they are following a reducto ad sillyness path.
Really do you let your boys play "cowboys & indians"? "Cops & robbers"? If you do then aree you training them to have a fantasy about murder, or life on the run from the law?
