This doesn't feel like a Humble Bundle to me. I loved Humble for spotlighting great Indie games. If I want cheap older triple-A titles I'll buy them during a steam sale.
It is great that it's all going to charity, and as you said, kudos to Origin for that. I just don't like the direction Humble is going. I want them to be a place I can go to find interesting Indie games I might not have heard of before.
Also, it's hard to find these games on a Steam sale for this cheap. I could get one, maybe two for what I just paid for the bundle.
edit: It appears that even if they use Origin (blarg), many can still be installed with Steam:
- Crysis 2 Maximum Edition - Dead Space 1 - Burnout Paradise: The Ultimate Box - Mirror's Edge - Medal of Honor
