I already own the basic game, but now I might have to buy the collection just to get all the DLC too.

[Nostromo]

What a deal. I already own the 2 Nostromo based dlc's. Should I get this? What am I missing.

[Local Trouble]

I haven't played it much yet.  To be honest, it seems boring.  However, I do acknowledge that it has many fans and I like seeing the Alien brand done justice for a change.
