Monster Hunter Mania
The Monster Hunter Portable games are generally understood to be the reason why the PSP sells so well in Japan. This WSJ article explores the monster hunter craze, the appeal of face-to-face social play, and how the game ain’t just for teens. It also points out that Monster Hunter might be singlehandedly responsible for doubling the PSP’s sales. Doesn’t mention that Capcom puts out a new DLC quest once a week.
Man, now I feel like grilling some monster meat.
