Famed designer Sid Meier established and defined the submarine simulation 22 years ago with the classic Silent Service. Although the genre has seen better days, it continues to plug along thanks to Ubisoft's solid Silent Hunter series. 2005's Silent Hunter III was the last release in the series and let you captain a German U-boat in the Atlantic during World War II. Now with Silent Hunter 4: Wolves of the Pacific, you play as an American submarine skipper battling against Japan. In many ways, Silent Hunter 4 doesn't veer too far from the formula found in Silent Service and is a faithful successor to that seminal game.
