Does this have a sort of "jump point" to get places? Running around for miles in AC3 is what lost me for this franchise and that's all I can think about when wanting to play AC4.
And I LOVED every AC before then.
You mean Fast Travel? Yes.
All the major cities and even mini-islands can be fast-traveled to once you discover them and "Synchronize".
Even in the cities (Kingston, Nassau and Havana), you can fast-trave; between Sync points once you discover them.
So yes, very easy to get around once you discover the various locales.
