Mafia 2

Mafia 2 is an open-world action and TPS game. It's set in the 1940's - 1950s, over a long and quite immersive story. You are Tony Scaletta, a Sicilian immigrant who is shipped off to the Italian front in World War 2 after getting into Italian shenanigans with your best bro Joe. The story picks up after you're sent home for good, thanks to Joe, and you gotta make a living. The gameplay is solid, the world doesn't have much to it, though. It's a story-centered game, not GTA "fuck around and run over grandmas lololololol" esque. Give it a try, the port is solid. There's also a multiplayer mod ala SA:MP.
