I imported this game on ps3 about three months ago and though the menus were in Korean I managed to complete the game (the dialogue was in english - phew!)
It's the first open world survival horror which is basically a kinda hybrid of GTA, Silent Hill and Resident Evil. You control Francis Morgan, an FBI agent sent to investigate the murder of a young girl in a town called Greenvale. I don't want to spoil it but I can assure you that this game has a riveting story with lots of twists and turns, weird and eccentric characters and some really entertaining dialogue. It's quite a long game, about 20-25 hours and there are also lots of optional side quests to do along the way.
It's a strange game because even though the graphics aren't the best the game really hooks you in. I can safely say that you have never played a game quite like DP. It's ambitious, witty, smart and scary and though it may not be the best looking game you've ever played it might well be the most memorable.
