Sell me the game

Hi, I recently looked up some things about the game and found It pretty interesting. That said, with time I've become picky with my games, so I was pondering whether to actually buy It or not.

So, I've played a lot of Assassin's Creed games, probably missed only Rogue and the others after Odyssey. But, to be fair, I don't really care if the game is a good AC game. Question is: is it a good Viking-game? Can I enjoy all the various Viking-activities? Is the setting good, detailed and atmospherical? I loved Ancient Greece and Late Ellenistic Egypt so is this portrayal of England good, better, worse? Are Dlcs worth It? The Paris' Siege one concept really got me hyped but I want to be sure they're worth the additional expense.

Thank you in advance and sorry if there are some errors, english isn't my first language.
