What is your opinion on the video game Second Life?

There’s this game I just recently heard of called Second Life. It’s a viritual reality Instant Message game of where you can meet and chat with people in a virtual world. You actually put your real money into the game to convert to Linden Dollars ($1 = 700 Linden Dollars) to buy your own property, set up your own store shops, buy your own house, etc. It basically is like living a second life. People pay Linden Dollars to other people who are “psychologists” in second life to get advice and help, when in reality, these “psychologists” are just ordinary average joe’s down the street. What is your opinion of this game?
