They got your quivering in fear needs all covered with Amnesia, your beating things up with a hammer needs with Bastion, your Tim Schafering with Psychonauts, your creepy 2D indie dying horrible deaths needs taken care of with Limbo and uh... I'm not exactly sure what you do in Sword and Sworcery, but you can get that as well. Also Charity.
e: Soundtracks for all the games included as FLAC & mp3.
e2: They added a bunch more games: Lone Survivor, Braid & Super Meat Boy, which is pretty neat. I don't think they included soundtracks for those. Also you get the games if you already bought the bundle, or if you are going to buy it, you will have to beat the average.
