Not sure if anyone has heard of this, Catherine
, but it's a fantastic story game. I'm presently over 50% through the game and it is a very interesting story, with numerous intersecting threads. I have suspicions about how it will end, but I really like how it is not a linear story and it seems to prey upon the player's fears from time to time.
I can't really say much more without talking about all the details.
But if you are looking for a non-traditional video game inspired by non-linear story-telling, this is a good game.
