Welcome to the forum!
Yeah, I must say I was *very* (pleasantly) surprised by the news of DLC set (apparently) in Mayan ruins....I'm wondering if it's still supposed to be in the 1770s, though. That's a *looooong* way away from colonial America, and I can't help but wonder how (and why) Connor would go so far away from his home.
Makes me wonder if there's more DLC/main game maps that are set there....maybe it's a Desmond thing, set in 2012 to tie in with the overhyped apocalypse scenario.
There wasn't a whole lotta building (at all) from Native American cultures, pre-Columbus. And the pre-Columbus European settlers/explorers left almost nothing to indicate they'd even been here, to the point that scholars still hotly debate whether or not there was any European/Asian/African contact at all prior to 1492. And the European settlers after Columbus, as that GI article pointed out, rarely built anything to last. Yes, New York and Boston were settled in the early 1600s, but almost nothing remained of the original settlements in 1776. Americans were (and are) a very transitory people.
That being said, I think Spider-Who is probably spot on about the same platform dynamic being there, but in a makeshift colonial frontier motif that would look contemporary to the rest of Connor's world.
Or maybe Ubisoft is going to the *other* extreme, and making platforming that isn't
ancient at all --- or at least, doesn't look ancient. Maybe Connor discovers secret lairs of the progenitors (or whatever the hell Minerva's group is actually called)...
Also, the "Why You Don't Want AC Japan" article sums up my thoughts. While I trust that Ubisoft could do an outstanding job with any setting in any time period, I *didn't* want to see them move the franchise to medieval Japan or WWII or the modern world....the most overused and overabused milieus in all of gaming. Even with Ubisoft's great aesthetics and attention to historical detail, such settings have "BEEN THERE, DONE THAT, ENOUGH ALREADY" painted in giant flashing neon green letters all over 'em.
