More Assassin's Creed Brotherhood Singleplayer

Here is another interview going even into more detail about the Assassin's Creed: Brotherhood singleplayer and how much the game has changed and expanded. Key things to note is that the story mostly takes place in Rome (where as in Assassin's Creed 2 you spent time in Florence, Venice, and the countryside). This can be viewed as good or bad, but Rome is by far one of the most beautiful cities in the world and the Assassin's Creed games had really beautiful environments.
