After months of delay and some high-profile glitches, “Batman: Arkham Knight” has finally hit gamers’ screens around the world. But was it worth the wait? The fourth installment in the Arkham series sees the Dark Knight more tortured than ever as he seeks to rid his beloved Gotham of crime and tyranny, and it is a worthy finale. In a sign of the evolution of videogames, and their burgeoning budgets, the visual artistry and storyline are better than many Hollywood movies. And the gameplay, while not innovative, nicely refines features from previous episodes of a franchise that reinvented the comic-book crusader in videogames, much as Christopher Nolan’s “Dark Knight” trilogy did in films.
