I personally really enjoy the game, its fun, exciting and a new story which is how we probably get the story of Basim to the Valhalla ending.
The people bashing the game are making the complaint its copy paste, its a skin of another game, textures are bad, ETC! but the real question is why do these people keep buying the game every year instead of waiting for reviews?
I do feel like alot of these bad or negative reviews are people who don't enjoy games for what they are and are way to critical on what makes a game 10/10
Overall i love the Assassins creed franchise and looking forward to new ones to come.
