The World Undone: 1914 – Galitzia

From BoardGameGeek:

The World Undone: 1914 Galicia covers the Galicia Campaign using The World Undone original system inspired by the late John Young's take on the Marne by SPI. Units are divisions and smaller, turns are 1 day each, and a simple, low complexity rules engine makes it possible to simulate the entire campaign in less than 2-3 hours. Players can combine the Galicia, East Prussia and Serbia Games together to simulate the entire Eastern Front in 1914. -description from the publisher
