I'm more partial to the Ramses II--Merneptah era since it's technically the apex of the Egyptian empire (it started declining after Ramses III and falling into the grasp of foreign dynasties), but I guess situating it in the Ptolemaic period makes the country more colourful and adds opportunities (such as Alexandria and the Pharos lighthouse, which can be seen in this intro).
Not sure what to think about the disappearance of the minimap and the switch to a more Skyrim-ish navigation system (which I had nothing against, to make myself clear). I know people usually rolled their eyes when it comes to the AC collectibles (trinkets, feathers, bottles, etc) but I actually enjoyed running up and down buildings and terrains to find those, it helped me discover more locations and vistas (I remember two trinkets in AC3 that seemed almost impossible to reach unless you found a very specific path - it was a fun challenge in the end).
Anyway, even though I wasn't 100% impressed with the latest AC installments (I did however love the urban atmospheres those games conveyed), this one is practically a shoe-in for my (very short) list of games to buy later this year, if only for the fact that during my school years I was really fond of the ancient Egyptian civilization.
EDIT:
Remember that in AC2 there were, scattered throughout Italy, tombs of legendary members of the Assassins? The one found at the Basilica di San Marco in Venice housed the sarcophagus of
Amunet, a female assassin who achieved fame
Spoiler:
for having killed Cleopatra Philopator with the help of an asp.
Even though Aya, Bayek's would-be girlfriend (see second video), is apparently pledged to Cleopatra's service, Amunet's deed suggests there will be a falling-out that will at least materialize before or during Caesar's assassination and Marc Anthony's subsequent rebellion. Unless it was a mercy killing at Cleopatra's behest, following her defeat by Augustus. Either way, I predict some parallels with Unity, wherein the protagonist' love interest gets swallowed up by the conflict and dies in front of him, causing much angst.
Once again judging from the cinematic trailer, it's likewise highly likely that one of the main antagonists will be Cleopatra's brother-husband, Ptolemy XIII, with whom she grappled for Egypt's hegemony (Ptolemy would eventually die in curious circumstances after a failed bid to depose Cleopatra - cue in an Assassin mission to kill Ptolemy, with death by drowning required for 100% synchronicity?
).
EDIT bis:
Apparently Aya is Bayek's
wife, not his girlfriend. They're just living separatedly due to their different jobs. :-/
