I'm playing IL-2 Sturmovik: Battle of Stalingrad, a combat flight simulator by 777 Studios and 1C Game Studios.
Set during the winter snow of Russia during World War II, the campaign consists of five chapters where you must pass six randomly-generated missions in order to advance to the next set. The mission type options (intercept, escort, ground attack, ground support, or bombing) depend on the aircraft you have chosen from the roster of four for each side (two additional planes can be purchased for $40). While all of the aircraft are available from the start, successfully completing missions will unlock new skins and weapons. Despite featuring a fairly user friendly interface that can be turned off for increased realism, IL-2 Sturmovik: Battle of Stalingrad has no guided tutorials that explain the controls and lacks a manual. Quick missions, more scripted encounters, and online multiplayer are also available. The game relies on seemingly authentic plane handling and adjustable realism (manual engine and fuel control can be enabled, for example). Lethal weapons coupled with limited ammunition means you need to pick your shots, and the damage can be impressive when fire and missing wings are involved. The AI does an adequate job, although they do occasionally miss targets, run into allies, or shoot the player. While not a complete return to glory, IL-2 Sturmovik: Battle of Stalingrad is a solid entry in the combat flight simulator series.
