The Finnish Trilogy 1939-1945: Winter war 1939-1940 (vol. 1) (2012)

From the publisher:

The first game of the trilogy to be released is the famous Winter War between Finland and Soviet Union, which is often referred to as an epic battle between David and Goliath. Historically the campaign lasted for 105 days, but will you as the Finnish side be able to last that long, or maybe longer? The game can last up to 16 turns (Dec. I '39 - Mar. IV '40), but in the 3rd volume (The Lapland War), there will be an extended option with a possible Allied Intervention. Vol.1 Winter War will include special features like Soviet Prestige and Finnish Morale.

The object for the Soviet side is to capture as many important cities and factories as possible, as well as destroy the Finnish Army in an attempt to make the Finnish Morale Status plunge, which means the onset of peace negotiations. But time is not on the Red Army's side, a slow advance lowers the Soviet prestige, which can cause a negative outcome.
