Judging by the replies and interaaction generated by the OP, I think we can at least say that computer games *may* be a catalyst for community and social interaction!
Many good points have been made, but let me speak to the OP regarding his concern for balancing "fun" with the need for ministry. I am a pastor of a very active church, and have given my life to serve Christ and my fellow man. I also have a somewhat "obsessive" personality, in that I really get into things that I enjoy. One of those things is playing strategy games. Before PC games, I would play the Avalon Hill strategy board games (anyone here remember them?) If I couldn't find a partner, I would play them "solitaire!" Thankfully, I found a pastor friend who shared my love of these games.
Anyway, I do not believe that fun and relaxation are in conflict with fulfilling one's call and leading a productive life. In fact, I would argue that such relaxation, in proper balance, makes one more productive overall. Didn't the Lord himself set the principle for us in the Creation, where we are told that He "rested" on the 7th day? And even our Lord Jesus, we are told, often led His disciples to "come apart to a quiet place" away from the demands of their ministry. (As one older pastor once advised me, "You need to 'come apart' to relax, or you will 'fall apart.')
I love my life's work. In fact, I would say that I have "fun" 24/7! But sometimes I come home from a stressful day of dealing with people's pain and grief and confusion and weakness and ignorance and whatever, and I say to my wife "I've got to go blow something up!" ... and she knows what that means. I head to my PC and take on the Drengin hoards!
Despite the shrill and superficial responses of a few in this thread ("Methinks the lady doth protest too much!"), I admire your concern to find balance and proper focus in your life, and your courage in putting it out in such a public forum. I hope that what I have said can be counted with the many thoughtful and helpful replies you have already received.
BTW, do you always play as "Good"? I try to, but sometimes ...
