Mafia is easily the "Boss of All Bosses" in terms of its particular genre, need I say more? You'll want to get this game
So, Mafia's story is quite incredible and it puts you in the eyes of mob enforcer Tommy Angelo...
The opening credits quite simply says it all. It is all done cinematically and makes you feel like you are watching a classic mob movie. It all starts off in 'present day' w/ Tommy walking into a bar and meeting a police detective. Tommy is in need of protection from his boss so he turns to the police. The whole single player mode is played and told in 'flashback' sequences and steadily moves up to 'present day'. It is quite amazing how well this game is put together.
You have a wide variety of weapons and vehicle selection. And you walk around the fictional city of Lost Heaven w/ a sleek suit enforcing the 'law'... what more can you ask?...
