premise: IL-2 Sturmovik: Forgotten Battles (Russian: "Ил-2 Штурмовик: Забытые сражения" ), also known in Europe as Rebirth of Honor, is a combat flight simulator video game, and sequel to the 2001 combat flight simulation of the year "IL-2 Sturmovik" developed by the Russian software firm 1C. Unlike the first installment, Forgotten Battles focuses on the Soviet-Finnish Continuation War of 1941-1944.
hypothesis: Because Forgotten Battles focuses on the Soviet-Finnish culmination of the war in 1941-1944, the sequel is called Rebirth of Honor. 
reason: The first game was not called Forgotten Battles because it focused on the culmination of the battle. I replaced continuation with culmination. Regardless, "continuation" was what the second game focused on. In addition to this information, the name of the sequel does not have anything to do with the name of the previous game.
