However, there are aspects that concern me. It is amazingly efficient way to loose hours of time. Children who spend lots of time on computers seem to have different brain development to those who don't. The relevance of this we will have to wait and see.
The big thing for me is the normalisation of the abnormal. My son passed comment this morning that it was OK to loose on a game as you then just go suicidal! Other games normalise very realistically house to house clearances and other violent acts. Again the evidence is awaited but we know from history that normalising the abnormal is dangerous.
