They did give up on Altair though. Revelations was basically "cram together 5 pieces of Altair's life that take place in Masyaf, but leave out the actual exciting bits."

The only memories I liked of Altair's in ACR were Haras' assassination and the funeral pyre of Al Mualim. The rest were carbon copies from The Secret Crusade.
