In the midst of recruiters being told not to send WoW players to job interviews, BusinessWeek wrote an interesting piece about how World of Warcraft promotes innovation. The articles examines how Blizzard had designed a game that could probably be mimicked by any corporation looking to innovate. It's an interesting analysis of the game, with BusinessWeek saying that its players are motivated to achieve and solve tasks.
Although some readers counter that the achievement-oriented environment is normal for MMOs, one key insight is how WoW reduces barriers to entry and early advancement. More than most MMOs, World of Warcraft is easy to access -- it's easy to level and there are no harsh penalties for dying (unlike some MMOs where death results in a sharp XP loss, sometimes to the point of losing levels). In fact, some might even say that WoW is a little too casual-friendly. Even then, there's a lot in the game that drives people to perform.
The article recommends that corporate leaders take a look at the game and see how it creates a motivational environment. It even goes so far as to laud the gamer disposition, something that players have or develop. It's certainly a refreshing counterpoint to the idea that gamers (or WoW players, in particular) "cannot give 100%" to their jobs. So even though some companies might think that WoW is bad for their employees, BusinessWeek says it just might be good for the bosses.
