On the other hand, I found most of the DLCs completely harmless, if not even nice.I found half of the DLC to be completely worthless anyway. So for one to come out that a lot of people will enjoy is kind of silly for people to complain about.
New Game Plus. It can vary from title to title but generally you're able to start a new game and import the state of your player character from the end of your previous playthrough so they would retain their character level, skills, inventory, money - things like that. Sometimes all, sometimes only one of those features is used, it varies from game to game.
