I'm probably going to end up echoing what's been said before in this post, but that's not a bad thing...
I am also a highly stats-oriented, obsessive-ish, in-my-head planner, who really likes WoW. WotLK is coming out, so I'm spending a lot of my time thinking about tanking specs, class mechanics, professions, and class changes.
I do not, however, think that I am ignoring my Lord when I do so. God does not have to take a back seat just because I like a video game. I happen to believe that God loves the things that we do, because he loves us -- and that includes video games. I believe he gave me this kind of intellect for a reason, and even though I'm a bit obsessive, he's not afraid to get in there with me.
That being said, I'm not perfect, and WoW is a lot of fun. I often have to discipline myself so that it won't take over...
* Sometimes I am tempted to skip church or other fellowship-events so that I can play WoW. Those are the days that I make absolutely certain that I show up at church. WoW should not trump fellowshipping in contact with each other.
* When I said fellowshipping in contact with each other, I mean that I have taken steps to make WoW into a form of fellowship -- I am in a Christian guild and I have good relationships with people in my guild, and that means that I have fellowship with other believers in WoW. But that doesn't mean that WoW replaces contact fellowship. I don't eat with these people, we don't touch... it's not entirely the same. Contact fellowship is a huge thing.
* I make it a policy that if someone asks me to do something with them outside of WoW, I make that a higher priority than anything in WoW. Of course, prior commitments are prior commitments, and if the person in WoW happened to be my girlfriend (she just so happens to enjoy WoW as well,) then WoW might trump... but I try to keep it as a lower priority than contact with other people.
* I'm trying to remember to pray about WoW. We have this stupid notion that video-games are a no-God zone. I'm not good at this one, but perhaps it might be valid to pray for success and patience with others as you're getting ready for your third Aran attempt of the night.
* Remember that people in WoW are real people. Those real people need ministering to on a day-to-day basis. Try to be available to God to be his minister to those people.
I hope this helped and was not too overly rambley.
