Only problem I ever had were small glitches and some lagging that caused my game to kick me and start it back up. But honestly these problems might be solved if I connected to Internet and updated the game. Very quality game though personally, I deeply enjoyed the story line and gameplay sticking to the usual assassins creed controls. One thing I might suggest is deeper connections with the npc characters you can connect with like Randvi and others. All sounds wonderful game though. <3
