SOTC

For those of you who don't know (or don't care), the Tokyo Game Show is on this week and there are strong rumours that a HD version of Shadow of the Colossus will be announced at a Sony conference. For me and millions of other gamers, this is a big deal.
Shadow of the Colossus and it's predecessor are known as one of the greatest games of all time and the demand for HD versions of the games is extremely high.

SOTC in particular is a prime example of immersion in a game. The game begins with a strange warrior riding over a bridge carrying an unconscious maiden. They arrive at a temple where he lays her down on an alter. The temple is home to a mysterious voice which tasks the warrior with defeating several colossi in order to save the life of the maiden. And so the game begins....

The sense of loneliness in this game is fantastic and even though the protagonist never speaks, the player is easily and quickly immersed in the universe and the graphics still hold up to this day.
If you haven't played this game, you seriously need to. If you have never even heard of it, you truly are missing out on a classic.
