Do not put World of Warcraft, nor any video game, on a resume (whether you're in that game's 'leadership' or not).

Only exception being if I were applying to Blizzard.

I mention that I play wow on my resume, but I never actually say world of warcraft.

I say something along the lines that I'm a member of a club (guild), we do weekly events together (raids) and that I co-lead the events (MT and one of 2 raid leaders).
I dont use that exact wording, but I follow up with some of the responsibilities that could relate to my job such as showing up on time, being prepared ahead of time, communication, and resolving disputes.

I have only had one employer actually question what my hobby was about, and she only raised her eyebrow at it and laughed a lil.
It's never been an issue, and I have even been told that it helps employers see that I do other stuff outside of work other than drink, or get stoned, or just sit and watch TV.

Its all in how you present it.

HELLLLLLLLLLLL!!! NO!!!

Agreed, not that I am ashamed of WOW or anything, but the video game stereotype still has a few more years to be shaken away. Even as popular as WOW is, many people do not even know what WOW is. Putting it on your resume is pointless, because the people who play the game would rather not talk about it in their work place and the people who don't know what it is only see elves and orcs.

Perhaps there is that one HR manager who plays the game and fully understands what you are trying to convey. Though, in this job market, it pays to be concise and leave WOW to recreational time.

As Bobbo said; No.
The only way I would even mention it is if my interveiwer asks hobbies and I say gaming and and then they ask if I play WoW. Then I'd definately talk about the life skills it has taught me.

There is too much stigma that comes with playing WoW, if you're "hardcore" enough you consider it important enough for your resume then you may be "hardcore" enough to miss work in favour of gaming.

I would not put it on my resume or civer letter, but here is how I've used it...

I was at an interview for a programming job. The interview was not going very well - I knew i wouldn't be coming back for another interview. I had absolutely nothing to lose - so. when we were about done and he asked me what my hobbies were - I said - "I play a lot of World of Warcraft".

The interview did a 180 and we spent half an hour talking about Mmo's. I got the job. If you got nothing to lose - go for it. Thats my theory.

When I last applied for a job, I put WoW experience in my resume and that worked well. But I am MMO developer so I don't think that should count.

Bottom line - I feel sorry for anyone who has to hide who they are to get a paycheck.

If you think you have experience that is relevant to the job, share it. If they reject you because you're a gamer, then you, a gamer, don't want that job.

Now, If they reject you because you can't make a coherent statement linking that experience to the job, then you're not the best person for that job and you won't get it.
