The WB Bundle this week looks like a winner for me...

Batman: Arkham Asylum
F.E.A.R. 2
F.E.A.R. 3
Lord of the Rings: War in the North

Pay over the average to unlock

Scribblenauts Unlimited
Batman: Arkham City

I have Scribblenauts Unlimited on 3DS already but that or Arkham City are worth $5 on their own easily and the rest would be icing on the cake.
