Apparently in China a MMO called Dungeon and Fighter is 20% more popular than World of Warcraft. In itself not all that surprising until you watch a video of actual gameplay. It looks and plays like side scrolling beat-em-up from the earl '90s. I liked those games just fine...18 years ago. The appeal of an MMO with that playstyle completely eludes me. This is a clear case of different strokes for different folks.
To me this is also a good illustration of why it's idiotic to argue that one MMO is "better" than another MMO in any sort of objective sense. To (minimally) several million gamers Dungeon and Fighter, an MMO with almost laughably archaic gameplay by our standards, is more fun than any western MMO available.
