It is a matter of personal taste. I found it interesting, but I
hesitate buying the game standalone.

You can get a better result by reading the official forums. Try
looking for threads concerning "stories" about The Ship.
The true fun in the game involves the paranoia of other players. Since
they don't know their hunter, they generally look around in almost a
panicky state wondering who is following them.
