In spite of the fact that the game is essentially the same throughout the series as far as gameplay goes, they still manage to keep the series new and exciting. I find the story in the series to be quite entertaining.
The graphics continue to improve and this one doesn't disappoint. Check out the backgrounds and Ezio himself--amazing details. I like that they removed the emphasis on item collection since that can get tedious; leaving a limited amount of collecting to be done.
AC continues to build on the successes of its prequels and I look forward to playing the next chapter. On a personal note, I really liked Ezio and was pretty sad that this was his last game...according to what I hear anyway. Great job to the creators for making such an awesome character.
