It's worth the time to me, but I can definitely understand why others might not feel the same. Personally, I don't love the Viking "honour and glory" theme but I do like the zany "mystery" side quests and the overall game structure. As for whether it's a rinse-and-repeat of previous games... yeah, it is, in most meaningful ways. Since Origins, they've relied on a lot of the same mechanisms, but that's not a deal breaker to me. I like (modern) AC because of the visual polish and atmosphere, not necessarily unique gameplay. Odyssey was my favourite of the "new" gen of AC games, and I think Valhalla made a lot of tangible improvements to the mechanics and gameplay loops since that title.
