I'm only in the third sequence of it, but I'm now addicted to Brotherhood. It's put a lot of the good bits from the original game (the outfit is whiter, you do a lot more of helping people) and the map is absolutely massive. I genuinely can't believe just how big all of Rome is.
I really wish that I was on holiday just now, as what I really want to do is sit up until 3 playing the game.
Still... I have to go and put work together for next week.
I've even got the soundtrack on to download. It seems like everything that I've been listening to this year has either been a soundtrack or a podcast.
