I just bought it on the Steam sale for 11 Euros and I'm very excited.
Like many others I liked the first two Assassin's Creed games, but thought the series started to feel boring with Brotherhood, but then Black Flag came out and rocked.
Still I don't feel at all excited about Unity or Syndicate.
I wonder if the next game is still rumoured to go back in time, to ancient Egypt or something. That would be incredible.
