One of things that struck me about this episode is how hard it is to advance an existing franchise. Garnet said something like "lets get radical lets talk about hearts" during the Nintendo segment. Having never played a Zelda game I was like that is the most radical change they could make? An outsider it seemed trivial, but Jeff was so passionate about the elegance of the existing system.

Just making a new IP is not always a great an answer because as a publisher it is stupid to abandon a successful franchise just to chase a new game mechanic. Change is hard to get the audience to accept a lot of the times.
