After giving Far Cry 2 a shot, I will return, Darksiders has been a blast.  It seems to have a generally linear flow with just enough open world on the side to mix it up.

This is kind of spammy... You don't need to post your blogs to the forums, you know (I hear hiding it from the forums still completes the GB Quest).
 
Anyways, glad you're liking Darksiders.  I disliked it very much and I was glad when it was over.  I considered it repetitive and very boring.
