If parents want to understand what’s so appealing about MMORPGs (“massively multiplayer online role-playing games”), they might check out a new documentary on the subject, Second Skin. Of the 50 million people who play multiplayer online games, 50% feel they are addicted, the doc reports. It offers insights into who plays these videogames, such as EverQuest and World of Warcraft (the latter grosses $1.2 billion a year, Second Skin reports). Viewers meet all kinds of players, from those who say they’re addicted and how they became so to players who’ve fallen in love with each other in a game (before meeting offline) to “disabled players whose lives have been given new purpose to gold farmers, entrepreneurs and widows,” its creators say, adding that “Second Skin opens viewers’ eyes to a phenomenon that may permanently change the way human beings interact.” On the subject of dating, the doc (which is about 90 min. in length), says one in three women gamers date someone they met in a virtual world and that, for every one female gamer, there are 10 single male gamers. The Guardian gives it a thumbs-up. If you have the time and interest, it’s free for the viewing today here.
