IMO, game is not really "RPG-like" in terms of multiplayer, but there are RPG elements, excellent shooting mechanics, and stellar story. Some of the best DLC ever. The second one is better than the first but they are both amazing. I would highly recommend playing 1 and 2 before the pre-sequel. The RPG elements really only go as far as skill trees, looting, attributes, enemy and character health displays. That's about it.
