Way I see it:

Walking Dead DLC, Last of Us DLC, Bioshock Infinite DLC, those are meant for expansive gameplay and storyline.

Isolation is less of a gaming thing, but more for the fans of the franchise. 20 minutes isn't worth it, but at least people get it knowing "hey it's the real guys there.". It's more of a nice addition to an Alien collection if anything.
