Just picked up Assassin's Creed Brotherhood again after initially playing it for an hour or two and then getting bored.
I think i found it too hard, since i'd never played an AC game before, and wasn't really into it. But after playing and loving AC4, i went back to get me some more ass ass, and it's great.
I love just exploring Rome and restoring all the buildings while making money from owning shops. It's not quite pirating levels of fun, but it's good.
