Should I get South Park: The Stick of Truth?

[garretslarrity]

So South Park: The Stick of Truth is currently on sale on Steam for $13.59.  I love turn-based RPGs, and this one seems to be well received.  I wanted to hear what the VGC forum thought first.  Should I get it?

 

The DLC is also on sale, both packs cost $1.68.  Since I think the answer to my first question will be a landslide yes, I'd like to know if you think the DLC is worth it.  Was does it entail?  Is it worth the cost?

 

EDIT:  I have decided against any DLC.
