I saw a story once on television where a couple had gotten so obsessed with a game ( I think it was that World of Warcraft ) that they simply stopped going to work, paying bills, shopping for food for their kids, and were going to lose their house.
That can't be healthy.
*Friend* as long as you know how to distinguish real life from alternative life.
Tons of folks from Second Life, WoW, etc. find themselves in very precarious situations because they forgot - it was a game ;)
