Rating issues    
Violence itself is fairly mild with groups of human heroes entering your dungeon to attack your minions. No injuries are shown but once killed, corpses will remain visible for a long time, often in a puddle of their own blood, in order to affect a sense of realism which can impact on the overall game rating.
