Some people don't like it when main character of a popular series is changed. Just look at devil may cry...
There's a difference.
DMC is about Dante, since he's a half-demon, no need to worry about "in 20 years, he's too old!" plus he's kinda immortal so it's easy to keep on making games with him. The DmC game is now said to take place in a different universe (at first it was supposed to be a prequel to DMC3 or something, never looked into it), plus it's supposed to be "Dante" which a lot of fans are raging about.
AC was about some guy in the present (or future depending how you look at it) who gets captured and probed, looking at his ancestors and trying to find clues. We play as Altair in the first, Ezio for the three games that just came out and apparently John Redcorn's ancestor in this new one. It is normal to play as other characters besides the 'original' title character in this series.
