I just hope the new chapter has a story that was not written by a 13-year old. And as for role-playing content, you actually get to make ONE choice in the game - the faction you want to belong to! It's not much, but hey, it's a start in trying to fulfil its claim of being a "Role Playing Game".
I'm still going to pre-order it though
... I think it's a fantastic co-operative and competitive action/adventure game
