World of Warcraft is undoubtedly the most successful, profitable, and most-played game of all-time. There's a reason for that - it's built to be more addictive than heroin (but without any messy needles). And for over ten years, it's been enormously effective at hooking players and expanding its world - and consuming countless lives in the process. Really, WoW is as responsible for more shattered careers and friendships than maybe anything else. It demands your constant attention and is enormously difficult to escape. It's not a videogame - it's a monster.
...a really, really fun monster. So pumped for Warlords of Draenor.
