The latest Indie Bundle is up! For whatever price you decide on, you get Bastion, Amnesia: The Dark Descent, Psychonauts, and Limbo (Bastion only if you go over the average donation, which was $6.89 when I donated). The money raised from this goes to the EFF and Child's Play Charities. It's a great deal for a great cause. I donated $10 and got over $100 worth of games. The best part is that the codes are good forever and can be used on whatever computers you have and will ever have.
