What should i get in November assassins creed brotherhood or black ops its hard to choose theyre both good but i can only have 1 of them tell me what should i get and why

Simple awnser?? Assassins Creed Brotherhood because in those games you can free roam and you can stil shoot like with a crossbow (i think) and you've got new abilities like riding a horse IN a city and you can man a canon. So my choice Assassins Creed Brotherhood but if you don't know the storys of the other games then its hard to understand youre choice.
