Total War: Shogun 2Edit
Echigo is home to the Uesugi Clan. Echigo's massive size makes it difficult to invade or attack from, particularly in the early game when roads are not upgraded. It also borders many provinces, making the Uesugi starting position a precarious one as it can be invaded by multiple factions.
Echigo is the only province in the eastern half of the map to have a naval tradition, boosting trade profits of any faction that owns it. This handily stacks with the Uesugi Clan's innately increased trade income, and makes it a useful target for the Date Clan, Takeda Clan, Hojo Clan, and the Ikko Ikki.
