Thinking of picking up Mafia II in a couple of weeks, but you never played the original? You might want to try Steam.
That's because 2K is offering the first Mafia for free to anyone who "pre-purchases" Mafia II over Steam.
Although the sequel doesn't continue the same story, it's still worth checking out. Both games are set in the same world, and you'll be able to spot a few references and cameo appearances in the sequel if you've played the first.
