Do you think the franchise will return to the old mechanics in a game taking place in the main Assassin"s Creed timeline (from when the current brotherhood was established to the modern day)? I think part of the reason why they went with the Ancient Trilogy (Origins, Odyssey, and the final one taking place in Rome) was to bypass old mechanics and narrative restrains. It gave the franchise much needed nuances but after replaying Unity, I really miss the old mechanics. Plus while i understand the maps in the last two games were huge, the smaller maps allowed for better detail which made the emersion better.
I'm partially writing this because the final dlc episode of Odyssey kinda marked a low point for me in the franchise. Along with the Hades map, Atlantis was bland to me. And from a narrative point of view, i wasn't invested as much as I was with the first episode. Then the fact that Kassandra?Alexios becomes a Kratos like character by the end was a bit much. Hopefully there will be a reason to this gameplay change in the year two content but as seeing as how events from Legacy of the first blade had no real substance in the Fate of Atlantis, I doubt it.
