Assassin's Creed II shatters expectations. It's bigger, more complex, better looking, and more fun to play than its predecessor. That first game set the bar for innovation in action games, establishing a unique control mechanic, a nuanced and clever approach to plot development, and an overriding concept unlike anything in the gaming milieu. In many ways, the sequel is far less innovative. Ubisoft Montreal improved all of the standout features, but it didn't push the envelope. Instead, the team used this go-around to fix problems, perfect their strengths, and, perhaps most importantly, model some of the tent-pole ideas of other games. 9.5/10
