I played through the demo and it was the same all the way through. Kill this group of monsters. Grab their stuff. If their stuff is better, use it. If not, toss it. Kill next group of monsters. Occaisionally you find someone that will follow you around and attempt to help you kill monsters. They are generally ok at it. It's all kind of like Diablo, except that you have followers and you kill more stuff. It's still quite boring after an hour or so though.
