This game does not feel like an AC game.
If you play AC because you like how the flow of running and jumping feels from place to place then this game is not for you. Controls are clunky and because it takes place in the mountains there are very few places to do the parkour that AC is known for. The sync points often do not have a way to dive off. The longship is clunky and annoying to steer. Stealth is nearly useless. Most of the combat involves running straight at a group of the enemy and fighting with your Viking raiders.
Don't get me wrong, the game is beautiful and could be fun if you just want to run at people and kill them similar to god of war without the cool combos. But if you want an AC game with the classic AC style, this game will disappoint you.
