I liked Brotherhood on the PS3 and at the time the quality was very good (gameplay) but not as good as the promotions (trailer).
The most recent games are amazing – Assassin’s Creed Syndicate
And they’re working on a new game, which seems to be a bit delayed: News
There’s a movie coming out at the end of 2016 – trailer
