Persona 4
Persona 4 is a role-playing video game developed and published by Atlus for Sony's PlayStation 2, and chronologically the fifth installment in the "Persona" series, itself a part of the larger "Megami Tensei" franchise. The game was released in Japan in July 2008, North America in December 2008, and Europe in March 2009. "Persona 4" takes place in a fictional Japanese countryside and is indirectly related to earlier "Persona" games. The player-named protagonist is a high-school student who moved into the countryside from the city for a year. During his year-long stay, he becomes involved in investigating mysterious murders while harnessing the power of summoning Persona. The game features a weather forecast system with events happening on foggy days to replace the moon phase system implemented in the previous games.

Media Create stated that the game's outstanding sales that surpassed the debuts of other titles from "Persona" series may be due to the exposure the "Persona 4" game has had in other forms of media. As of mid-July 2012, the game had sold 193,412 units in Japan. The game was the eighth most purchased digital Vita game on the Japanese PlayStation Network in 2013.
