Worth buying

I must agree, making games come out every year is a shitty idea. Though I liked Brotherhood, Revelations and beyond lost their light.

Brotherhood was better than AC2.

Brotherhood and AC II had some of the worst dialogue and story telling in the series. You want interesting, morally ambiguous targets? Here are some nobles for you to kill. Want a serious story that discusses the difference between right and wrong, truth, reality, freedom, ...? Here's a boring revenge tale featuring Italian aristocracy. The original Assassin's Creed is by far the best in the series and Revelations and AC III at least tried to improve the story (sadly the ALIENS! story arc - introduced by AC II - was beyond saving).

Eh, multiplayer is decent but a complete rip off of "The Ship". Plus it's pretty much dead.

Allthough Revolution is cheaper
