The early guild 3 minimum system specs indicate a game relatively light on CPU, asking for a dual core, but the min GPU analysis is more demanding, requiring an Nvidia GTX 470 or similar AMD card. Modern PCs should have no problem meeting these hardware specs. The min RAM requirement is also pretty low, at 4GB.
The Guild 3 is a sea trade simulation that takes place during the late Middle Ages. Step into the shoes of a citizen, acquire businesses and mansions, produce goods and trade them, start intrigues in politics and society, love, hate, bribe, fight and live through good and bad times!
