Assassins creed Brotherhood.

ive noticed that in the first time i played i missed alot, becaus i almost only went for the main story!!
thats wy i didnt like it 100%
but now i do really like it since i aim to do everything, all side missions etc etc.
it takes alot more time (wich is always good) and now i see the use of the Brotherhood, wich in the first x only anoyed me.
