Many people believe that MMO's are too involved that they are too much to take on.  Granted there are some folks that will never like the genre.  As the old saying goes "different strokes for different folks".  But for myself I will probably never go back to the old style of gameing again.  I tried a single player game (Oblivion) for the first time in many monthes last night and found that while I did have a great time and enjoyed myself I missed the fun of talking on vent to the guy next to me, or sharing with my guild/clan in the fat loot we just got.  It scares me a little bit that sitting in front of my comp can almost feel as social as going out to the bars but thaks to the MMO genre it has done just that.
