DLC
There are 3 DLC missions for this game, Joes Adventure, The Betrayal of Jimmy, and Jimmy's Vendetta. They are good and actually give you a reason for having such a huge city to work in, they utilize many areas that you just drive through for no purpose. Don't expect any kind fo storyline here, which is a failure in my opinion, but it is beautifully crafted in its action and settings.
If you like the driving side Joe's adventure is your game, a lot of driving action with him, although he does find time to fight and shoot as well, I kind of like the grocery store heist in this one. Almost all of it takes place while Vito is in prison, but one big standout is the first mission which coincides with Vito being arrested and Joe needing to silence the witness responsible for the arrest. It ties the story's together and is really well crafted in its shooting and driving sequences
If shooting is your game, Jimmy is your man! Although he is not introduced to you during the main game he is handed to you as if you've known him all your life, but whatevs. There is definitely driving for Jimmy, but he is a master sociopath unwilling to accept a world in which gun violence is not just an option, but your best first option for any conflict resolution.
