I don't quite think so and I felt the way about Legends & Killers. These things seem that they mostly needed to be included in the shipped game. I can't see comparing 1/6 of RDR's content or scope to this paltry offering especially considering the amount of work R* did comparatively. 5$? Absolutely. IDK why the default DLC price is $10 and the (new) default game price is leaning toward $15. Maybe the latter bit is me just being jaded by the Summer of Arcade. 
 
Anyway, are you all gonna pick this up? Do you think it's worth $10?

Nope, as you said.

Apparently, Kotaku says that of the four planned DLCs, this one includes two of them as they weren't planning on charging for the Free Roam one, but MS & Sony only allow one free pack a game(?), which would be the Outlaws to the End Co-Op pack. I'm still not having it. We'll see about the Undead pack, but I doubt I'll be pushed over the edge...

I dunno, seems pretty cool...
