After putting 110 hours into the game i can safely safely say then AC Valhalla is the best assassin's creed game that I played in not the perfect experience by any means, yes it has its flaws specially the annoying bugs which I hope will be addressed with the passage of time but overall is the best experience.
The combat is great they perfectly capture the Vikings fighting style and gore animation, the main criticism they answered from the pervious game is the quest design they improved a lot of them, now you can go toward your main story our pursue side mission and gears.
You don't have to complete the unnecessary side quests to level up the player to take on the main story missions.
The story is not assassins focused but they are selling you the idea of what is to Viking raider in the 9th century England and I like that part.
Now they should finish the series with last trilogy of games and explore the assassin's creed in other medium of entertainment.
