I absolutely loved The Saboteur! There was nothing like roaming an open world Paris (this was 5 years before Assassin's Creed would do it), and the theme of rebellion against the Nazi occupation was an awesome change compared to WWII games of the era, with a neat mechanic of turning areas of the game from black and white to colour as the rebellion took hold. Despite the fact that the song wouldn't come out until 20 years after the game's events real life, driving through Paris listening to Nina Simone's Feelin' Good absolutely nailed the feeling of the setting. I can't fathom how many times I got in and out of a car just to reset the radio in the hope that that song would come back on before I started any drive.
