If you've never heard of Bastion, now is the time to learn.
The game is beautiful and fun to play. The story is deep, with an interesting world and even more interesting characters. And the music... ah, the music.
Bastion has probably the best soundtrack I've ever heard. I fell in love with it the instant I heard it, and I bought the music soon after buying the game. The unique blend of styles, the heavy beats, the heartfelt melodies...
I admit I put the disc in the car a few months ago, and it almost never leaves the player. I've listened to the whole CD some sixty times over, and I'm totally obsessed. Frankly, it's amazing.
Go buy the game. Or at least the soundtrack. It's totally worth it.
