As far as you can go for a good game at this darn age.
Please note.
Audio: Not so well synced and in ceremonies please get rid of whispers if it has nothing to do with the ceremony. It sounds like WOW pub. And most of all animation of characters should have sounds when they spit in there dialogue.
Character animation: rather then doing nothing than do something useless. For instance, carve a stone unendlessly. Eat a apple that doesn’t have a bite on it. Kahootz much?
Graphics: Lovely but textures are poor for environmental animals/birds. Seagullls still look like paper planes! Trees not so real and the game shakes so much as it’s a hurricane.
Game physics: Is like two worlds. No matter how hard the difficulty is, game can be easily beat with stupid old style of combat. On hard not once I have used shield as it was never needed when charging. Bow men are a bad aim not once they get me head on unless I stand still.
UI extra it’s all about development but so far in assassin series it’s getting better.
