A two button game.
Storyline is great. You got all the characters of the chosen era, even the ones that made little contributions to the history of the US.
Stealth is totally disappointing, and get's worse if you realize that you are playing an assassins' game.
The battleship combat is the highest note of the entire game. It's pretty simple but still amazing, and that's why we have Black Flag now.
First Assassin's Creed game that I've played and to me was a huge deception. If all the others are like this one then this series are just OVERRATED.
Good game, but NOT great.
