See thats what I mean about different tastes. I own all the AC games, I never finished a single one of them (let alone 100% them), until AC:Origins. Origins was the first AC game that I not only finished but even went on to 100% it. I did the same with Odyssey. Like many many people I felt that the AC games needed a shake up, they had become very stale and although neither Origins nor Odyssey are particularly AC-esque, I do feel that as Games they are far better than the previous incarnations of AC. Everyone has different tastes though for me, Odyssey is without a shadow of a doubt the game of the year for 2018 but for others, Fortnite will be the game of the year, a game that I consider to be an abomination, which just highlights that everyone is different
Not really sure about the comparison of Ark/Atlas and Odyssey as looking the same environmentally though. Both Origins and Odyssey look way WAY better than Ark or Atlas, at least on my system they do. No idea why its looking like that on yours or performing like that on yours given that you have a better video card than me (and probably a better PC overall than me).
