It's definitely one of the better Assassin's Creed DLCs until that point, which isn't saying much at all. The main story, while it feels like a very fitting epilogue to the story told in the main game, it still is detached enought that it does not feel like it was cut from the main game. It's a good addition to the lore, especially in exploring how the early Assassin's/Hidden Ones operated, and definitely a must for the series fans.
The problem is that Sinai is rather a dull place. Like much of this DLC, Sinai also feels more of the same, with the similar arid mountains and surprisingly unintentersting urban areas. The gameplay also does not have any changes, which is a shame since they could've definitely incorporated the idea of apprentices into a more concrete gameplay mechanic (i.e. summons from Brotherhood). Still, one cannot be complaining too much considering the amount of content and quality it offers with its price.
