Feel mixed about that idea. I would say that a Star Wars game doesnt require that unique hook in that uncharted in Star Wars would get people pretty juiced, but then you see something like Shadow of Mordor really capture peoples attention with a unique hook (the nemesis system).
What really struck me was the truth that it is unreasonable to expect a new team (for that genre, at least) to compete with uncharted 4 in the first iteration - especially with a smaller staff.
