Yup, I still play very occassionly (when my wife's work schedule allows).
My eldest son is approaching 7 years old so in a year or 2 I will introduce him to D&D and then I can play at home

4th edition is certainly a bit different to 3.5, but it is still good fun. It has borrowed alot from MMORPG but that should prove beneificial in attracting the WOW crowd and those familiar with MMORPGs as well as those of us who are old timers.
The good thing is, as always, you can play it any way you like. Some groups like the free form style and don't use miniatures while other groups treat it almost like a tactical miniatures game with a splash of role-playing. Thats the beauty of the system, it can be adapted to suit most styles of play.
Hope you enjoy it
