I completely disagree with the guy. If you fill your company up with high level WoW players rather than Harvard MBA’s you’ll soon be bankrupt. The problem is that to be a high end raider in a game like Warcraft, you need to devote a significant chunk of your life to the game. The kind of people willing to do that are not going to make good employees, working hard on boring, real-life projects. They’ll be spending their day thinking how they could rather be grinding the next level of their crafting skill or some shit like that.
In fact I think there could be an inverse relationship between how succesful you are at the game and how big a loser you are in life.
