Kawanakajima no Kassen

Not to be confused with the actual Battle of Kawanakajima.

Kawanakajima no Tatakai (川中島の合戦, Battle of Kawanakajima) is a war simulation title based on the Battle of Kawanakajima. This was the first video game sold by Koei founder Kou Shibusawa who initially made it as a hobby.

For its 35th anniversary, a modified port of the game will be included in the Treasure Box edition of Sangokushi 13 Power-Up Kit. It contains two modes: the original version and a remake with enhanced graphics as well as easier gameplay.

Gameplay
As the Takeda, players are tasked with defeating the Uesugi by leading a formation of units to battle. Units are color-coded to designate their respective classes. When moving from one area to another, the map's coordinates will change to reflect the player's current position.
