no offense intended, but i personally believe that second life is far too "free roaming". the fact that you are able to do virtually anything may lead to users believing that second life is their "second life". the user may lose grip on their own reality as second life becomes their new reality; they may be enveloped so much by their "god-like" power and anonymity, that their own life may appear as dull and boring. the user may forget about improving his/her career or accomplishing their schoolwork, and may, in fact, spend countless hours playing a game, and looking forward to playing a game, that achieves nothing in life. i see it as being highly addictive, dangerous, and destructive.
P.S. please refrain from spamming as it is not appreciated on this board. saying it once is enough. do not be surprised if your post is edited by a mod.
