The graphics and the in-game world details are amazing. I find Assassin's Creed's characters are never very memorable and this game is no exception, however the detailed world map with its temples, cities and deserts makes up for that.
The gameplay isn't as smooth as I'd like it to be, the crawling sometimes blocks, it's hard to hit soldiers (on horses). Also the button mapping takes some getting use to: dodging with square, interacting with triangle, crawling with x. It's somehow very unintuitive.
