The best in the series... yep!
The graphics are great and really well done. I think the best part are the landscapes. With just how beautiful the cities are, it gives a wonderful experience.
Story: 9.5/10
The story is really, really, really good. It gets to the point and it is huge! It is easily the biggest story in all the Assassins Creed games. The ending of it is onne of favourite endings in any game ever. So, all around, a magnificent story.
Gameplay: 8.5/10
The gameplay is a very good. There are a lot of weapons you can buy. There are some flaws with it though. Like you can't kick and sometimes it feels a bit repetetive. But it's okay that it is repetetive because the gameplay is fun anyway.
Content: 9.5/10
Sure there's no multyplayer, or any other extra game modes, but the story mode is so long, that you won't really care. After you've done the story, you can still find all the feathers, complete the assassins tombs, find all the treasures, buy all the weapons, upgrade the villa and synchronize all viewpoints. So much to do!
Overall: 9/10
