I was blown away by Ghost Trick: Phantom Detective. Every element works in perfect harmony. The unique gameplay mechanics (two buttons, Ghost and Trick? Amazing.), Shu Takumi's clever writing, bold art direction, and banger soundtrack all support one another and build off each other's strengths. A perfect example of a video game that could only be a video game. Also, can't comment on this game without mentioning the all-time great video game dog, Missile. This has immediately entered my personal canon.
