I'm about 40 hours in and only have about 30% of the map uncovered according to Ubisoft SAM
I still much prefer Origins to Odyssey, I think the tightness has suffered loads from the branching questlines and sub plots. They get fractured and lose their impact. Honestly, I would have been happy with Deimos and the cult without all the Myrrine, Nikolaos and fleet side tasks. The bounty hunters plus the mercenaries all seems a bit too much as well. Also the environment is very juddery, stop/start due to getting caught on some rocks at heights you'd expect to auto continue etc. There are way more forts in Odyssey and the balance of drawing soldiers is off for those wanting to assassin silently. There's also no effort to hide the copy/paste nature in the game, at least in Origins most were grafted into the world a little more seamlessly.
The controls feel worse/clunkier than in Origins. Sticking a crit on a button hold while behind someone is stupid. Use an L1/L2 + triangle for example. The equipping torches to burn war supplies was tedious as well.
I've grown accustomed to the skill trees. I still think they're a bit superfluous. Putting ping on a skill then locking some behind advancing the spear as well. I think Origins didn't rely so heavily on perks providing essential crits, and I don't like splitting damage as +% on clothes and items. Having loadouts but being limited by archetype skill tress seems to be at odds with the design. I also preferred playing both protags like Evie/Jacob than splitting the way Odyssey did.
Beautiful game but I wonder if those that love Odyssey played Origins. Even the sidequests in Origins to me were more memorable and the world including thing like the circle stones was just more cohesive. Compring the impact of Phoibe to Shadya is a perfect example to how much more invested in Origins lore and world I was. Anyway, still enjoying it largely - I just feel as a stepping stone from Origins to where Ubi want to get with a more RPG-like experience, this gets the balance between action, progression and engagement a little wrong.
