Assassins Creed 2 was an amazing game. The gameplay is great. running through the streets, climbing buildings, jumping off of stuff and killing bad guys the whole time. Its hard to beat. Everything in the game is based on killing bad guys. There are no missions where you sit on a bench and listen or do something boring, like in AC1. All in all one of my favorite games of all time.

I can't speak for Mafia 2 because I haven't played it.

There is a cool video about AC2 it here:
