Although we recognise that it may be difficult to stop younger kids playing these types of games when older siblings are playing/ other kids they know, however, the severity of the unsuitability of these games should not be underestimated. If you are going to allow your kids to play, doors should be open and headsets should not be used. However, a good idea would be an agreement between parents in a class regarding games like this as if all kids are not allowed to play this game it is easier for them to accept than if just a few children are not allowed.
