From Wikipedia Pacific Theater of Operations (P.T.O.) (Teitoku no Ketsudan) is a console strategy game released by Koei in 1993. It was available for play on the Sega Genesis and Super Nintendo (SNES) platforms. Players could assume one side of the Pacific Theater of Operations during World War II, acting as naval commander, organizing fleets, building new ships, appropriating supplies and fuel, and even engaging in diplomacy with other countries. The player can choose one of several World War Two battles to simulate, or could control the entire Pacific campaign well before the Attack on Pearl Harbor. A sequel, P.T.O. II, was released by Koei in 1995. The next version to be released in America was P.T.O. IV for the PlayStation 2, in 2002.
