The best Assassin's Creed game since Assassin's Creed 2.
This is coming from someone who hates pirates.

This game comes in three parts being a Assassin, being a ship captain, and being a ubi.... I mean Abstergo employee.

The Assassin part is similar to the previous games, but it is improved.
- Sword fighting feels alot better than previous games, its more Batman-like (Arkham games) and less Counter-kill spam.
- Range weapons are powerful, but not over powered.
- They finally put stealth mechanics in the game!!!! A game about Assassins!!!! (You can hide in bushes, long grass and are able to move around)
- Mission design is really good, and more varied than previous games.
- Side missions are amazing too, they range from under-sea diving to whaling to taking over forts.

Being a ship captain is the best part of the game.
- I enjoyed exploring the high seas more than the storyline, I kept exploring till the point where all that I could was the main storyline.
- Your Ship is upgradable and the system is extensive.
- Ship combat is great. It consists of shooting cannons at each other and then boarding for some sword fighting to capture the ship. Its really addicting.

Being a ubisoft employee is in first person, and you mainly do hacking puzzels in it.
- Doing these puzzels unlocks background information, that is really interesting.

Multiplayer
- haven't touched it

Other Stuff
- Optimization could be better, but it is a beatiful game.
- Best play with a controller IMO, until you have to aim with a pistol.
- UPLAY :(

Rating: 10/10 -1 for UPLAY => 9/10
