Nope, you'll be good. It wouldn't hurt to watch a quick summary of the first one though. The second is one of the funniest games of all time. Tina is very likely going to be your favorite character. Idk if the dungeons and dragons DLC is included (I'd hope so at this point), but make sure to play it. That is one of the few DLCs I've ever bought that I felt was well worth the money.
