Igo Shinan '91 (Japan)

Igo Shinan '91 is a unique Go game for the NES, released in Japan. The main highlight of this title is not merely a standard Go match, but rather its role as an interactive textbook for the game of Go. The title "Igo Shinan" literally translates to "Go Guide," and true to its name, the game focuses on educating and training players of all skill levels.

Players will be introduced to the most fundamental concepts of Go, ranging from how to place black and white stones on the board, basic rules of play, to more complex strategies and principles. The game likely includes detailed tutorial modes, explaining concepts like "life and death," how to create "eyes" for survival, how to "connect" your own stones, and how to "cut" your opponent's stones. The concept of "territory" and scoring methods are also clearly explained.

A crucial part of the gameplay involves specially designed Go problems (tsumego). Players will face specific Go situations and must find the optimal move to solve the problem, for instance, making a group of stones live or capturing an opponent's group. These exercises help reinforce theoretical knowledge and develop strategic thinking.

Beyond the learning mode, Igo Shinan '91 also offers an exhibition mode against an Artificial Intelligence (AI) opponent. Players can choose various difficulty levels to challenge themselves and apply what they've learned in practical games. The game's interface is designed to be simple and clear, fitting the graphical capabilities of the NES, making it easy for players to follow the game and make decisions.

The ultimate goal of Igo Shinan '91 is to help beginners easily approach and appreciate the game of Go, while also providing a useful tool for experienced players to improve their skills. This is a highly educational title that deeply explores the intellectual beauty of Go.
