100%'ed. A better successor to Assassin's Creed II than Brotherhood. It's a shame that the game wasn't as well acclaimed due to franchise fatigue.

A compelling end to Ezio's and Altaïr's stories, with side characters far more developed than in Brotherhood. The story was well-paced and interesting, as were the side quests, and even collectibles and exploration.

Constantinople wasn't as large as Rome but traversing it was much more interesting and varied, with the use of the hookblade and ziplines.
The enemies were similar to previous titles but the addition of Janissaries was a refreshing take on the formula, as was the bomb usage and crafting system.

The faction challenges were interesting to pull off and never felt overly difficult or too easy, and were fun to do post-ending. Finally, I liked the Mediterranean Defense minigame as well as the deepened Assassin's Guild, with specific missions for your Assassin Den Masters.

Overall, a fantastic Assassin's Creed game which marked the end of an era.
