Humble Bundle: Scribblenauts Arkham Batman Series FEAR LOTR if you pay above average ($4.61 at writing), you can pay in bitcoins too! (which just reached new high)
The Humble WB Games Bundle
Six action-packed games to add to your collection. The Humble WB Games Bundle features six of the publisher’s top titles. Pay what you want and get the first installment of the critically-acclaimed Batman: Arkham franchise, Batman: Arkham Asylum Game of the Year Edition, as well as both of the intensely frightening paranormal shooters F.E.A.R. 2: Project Origin and F.E.A.R. 3 and the groundbreaking action-RPG, Lord of the Rings: War in the North! Pay more than the average and you’ll also unlock Scribblenauts Unlimited and the sequel to Arkham Asylum, Batman: Arkham City Game of the Year Edition.
Humble bundle accepts payments via bitcoins too! (via coinbase I think)
Bitcoin itself just crossed $266 its previous high
Updated with new additions: mainly DLC and FEAR1, bitcoin is about $430 now so the bundle at above average would be a bit over 0.01 bitcoin
