Limbo is probably the best game I've played in years. It's beautiful, and it lets you wade into it's world, without hitting you over the head, or doing lots of hand-holding.
The story is very minimal, but the world is so fantastic that it's just as fun to watch as it is to play. We need more unique voices singing different and interesting songs like this.
Ranting on, if every story is a heavy metal opus or poppy dance drone, we will go deaf, or at least be really really bored. It's the Michael Bay problem, if everything is exploding, then it's like nothing is exploding (think about it).
