If you own a 360 then I would say Daunte's Inferno or Darksiders (depends if u are a zelda fan i guess) as I was pretty impressed with the Daunte demo. However if you own a PS3 I would say GOW 3 as it pretty much sets the standard and none do it better.
I like GOW but I have a feeling I will just end up renting it, ignoring Daunte's and renting Darksiders as the zelda/GOW seems interesting.
