The original Assassin's Creed was a game that sharply divided gamers. There was one group who found that the game was needlessly repetitive and, for all intents and purposes, unplayable for that reason. There were only a few different types of side missions and you were required to complete a certain number of them before you could advance. It kept the game moving at a snail's pace. For some, the automatic nature of the movement in the game also kept things repetitive.
