I have this from x-mas.
Still haven't opened it sadly.
Mainly because I found brotherhood to be laughably easy.
Mainly because killing anyone turned into a "Do I have one of my 60 ranged munitions to poison/arrow/shoot/or throwing knife this guy in the face".
And the fact that in sticky "Oh stuff 50 guys out of nowhere!" situations you could just hold the right bumper and have your minions kill them all with precision and accuracy with one volley of arrows.
But I wouldn't stop that from you getting it. Especially if you're into the whole feeling like a ninja thing.
