Maybe you were thinking of not buying Assassins Creed Brotherhood? The below trailer would suggest that this a terrible mistake, resulting in crossbow wielding renaissance faire ninjas to drop from your nearest cathedral roof and do you great, great harm. It's also a very cool trailer, watch it.

Another subtitle for this game could be Assassins Creed: Eff Up the Catholic Church as the game seems to mostly revolve around turning cardinals, bishops, popes and swiss guards into jam squirting pin cushions. I wonder if you'll have the opportunity to carry out an assassination with your bare hands, you may even get to (snigger) choke a bishop (snort, snort, snigger). Ask your mum if you don't get it.

And in case you were wondering that song is Burn my Tomorrow by Unkle. It's going on my iPod as I type this.
