Not all its cracked up to be...
Its a good game yes, but 5/5 or 10/10? Absolutely not.
+Great Graphics
+Combat is fun and takes some skill to master
+- Storyline is average, nothing special but not bad
-Sound is just horrible, you can only listen to NPC guards yelling at citizens about stealing or saving someone and having them say they wish their sons were as brave as you so many times. Having played through the game and saving all the citizens you will hear the same 3-4 lines at least a dozen times each.
The assassination missions are where the fun is, but are only a small portion. The rest is filled with climbing dozens upon dozens of towers for POI's then sitting on a bench and eavesdropping or punching someone a few times to get information. After you realize that the entire game is the same 4 or 5 investigation techniques over and over again, which you need to repeat 9 times it gets repetative.
Disappointed me, i was hoping for the next big Hitman series. Instead i got Prince of Persia with a Crackdown do all these mini missions to kill the main guy. Still a good game though, although maybe not worthy of purchase if you have gamefly as there is almost zero replayability since the toughest decision you have to make later in the game is which guy to kill first.
