39. Brothers In Arms: Road To Hill 30 (2005)
Road to Hill 30 is an historical FPS developed by the people behind Borderlands. Granted, 2005 was way before dubstep became the soundtrack of Pandora, but WWII seemed a good as place as any to set a FPS. The title set itself apart from the endless WWII shooters by focusing on utilizing squad members, rather than punching a hole through enemy defenses by sheer might. You can also write the whole thing off as an interactive history experience. Like EPCOT Center, but with Nazis.
