And same goes with the story. In most games yes, the story is an important factor that carries the game forward, but in Hitman why do you need a story? Storyline in previous games hasn't really been that great and I understand it as it isn't the main point of the game. In SA you had to run errands all over the world to make the agency find vittorio. Contracts is flashbacks and in BM some dickwad is digging around old unsolvable murders. That is really all the storyline I need.
Agree with SancLunatic on everything.
I for one wouldn't care visiting old locations, I want to see something new!
