Alan Wake - even though Deadly Premonition offered way more than Alan Wake did, the amazing graphics (and way better than DP), the chilling atmosphere and good storytelling, make Alan Wake a good fit for the thriller genre.

Silent Hill Homecoming - in a way Deadly Premonition takes some features from the Silent Hill Series, so one would expect that they will be similar games. Well, Deadly Premonition has the best story in a psychological thriller genre, but Silent Hill Homecoming is a great game, with better graphics (which is not saying much), mind-screwing puzzles and instills psychosis into the player.

Silent Hill Origins (PSP) - pretty much follows the Silent Hill Homecoming description. Graphics-wise Deadly Premonition and Origins are on par.

Silent Hill Shattered Memories (PSP) - see Silent Hill Origins.
