I waited for almost two years for this game, and I am not disappointed.
I didn't want to give it a review until I beat it, but since I did not bring my 360 home with me to instead write my paper I will review it with about 1/3 of the game done.
The graphics are jaw dropping, and I am talking about in game graphics not cinamatics. And even though you do do the same thing it feels over and over again I am still addicted to doing them, so no I do not believe it is repetitive. That is like saying robbing cars in GTA gets repetitive. The story is interesting so far, might I add I almost cried when I found out what the game was really about (out of sadness not happiness) but the story seems to be pretty fun anywho.
Gameplay is extremely easy up to the point I am at. Everything you need to do is put on the map, time challenges give you more than enough time, your life replenishes very quickly, and fighting off dozens of people is way to easy... but since I was paranoid the game was going to be overly painful to play because of the difficulty I am content with the easiness.
All in all it is a fun game, you can run around on the roofs, and assassinate some higher ups. So go ahead and buy this game... just watch out for Mass Effect...
