21. Nine Hours Nine Persons Nine Doors (37)
This is a wonderful visual novel wrapped around a room escape game. This game uses the Nintendo DS and its medium in some of the most creative ways I've ever encountered, and surprisingly, for a story-telling purpose. Never before have I turned my handheld upside down because it made sense in the context of the story. I also loved that the story also breaks through the fourth wall to the player and gives reason for multiple playthroughs. The puzzles themselves provide a variety of interesting challenges and information. The mystery keeps you intrigued throughout the game and I was only annoyed that because I played through the route for the true ending the first playthrough I had to do the same set of doors twice.
Primarily an RPG player but have interest in any game that will make me think.
