Off topic, but I always figured Victorian London has to at least look way better than more contemporary London, which was essentially rebuilt after the Blitz. I visited 3 times during the 80s, and London has got to be the most boring looking Metropolis in the world. Of course that might have changed during the last 3 decades. I see images of London now with some more interesting modern architecture.
Of course, one problem with even exploring beautiful cities in Assassin’s Creed games is that you’re so often seeing a Roof’s eye view of the city. I love Paris in real life, it’s my favorite city, followed by San Francisco. But Paris is gorgeous at street level, but when you get a view from the top of Notre Dame, or from the Eiffel Tower, or from Sacre Coeur, all you see are these ugly rooftops. I haven’t played Assassin’s Creed Unity yet, but man, rooftops are the one really ugly part of Paris. I didn’t pay much attention to London rooftops, but I suspect I might feel the same about them.
