So you like the atmosphere and the story? Read a book/watch a movie.
RPG = Role Playing Game. Assumption is that there is a story for said role playing.
I play my RPGs mainly for the story, because gameplay isn't the most important thing in a RPG.
And besides, you can't get the same story from books and/or movies. It's reading and watching the Dead Space books/movies without playing the games. You miss a huge chuck of the story.
