My youngest SIL was playing House of the Dead at the age of 4, she thought it was hysterical, as did her parents and older brothers and sisters :( Also my DP has just given us his old PS2, and some games. Apparently the boys (age 7and5) love the wrestling and fighting games, which are 16+ rated. I have taken those games out, but DP and his whole family think I have over reacted! All my nephews, aged between 2 and 5, are allowed to play 18 rated games!
