SD Gundam Gaiden: Knight Gundam Monogatari - Ooinaru Isan (literally "SD Gundam Side Story: Knight Gundam Story - The Great Legacy") is a role-playing game developed and published by Angel (a subsidiary of Bandai) for the Super Famicom, released on October 4, 1991. The game is part of the SD Gundam Gaiden series, which reimagines Gundam characters in a fantasy medieval setting, where they become knights, wizards, and kings. This title is the third entry in the Knight Gundam sub-series, following the events of the previous games, and features a rich narrative, tactical combat, and a large cast of characters.
SD Gundam Gaiden is a turn-based tactical RPG, similar to the Fire Emblem and Super Robot Wars series. Players control a party of knights and heroes, moving them across a grid-based battlefield, positioning them strategically, and engaging in turn-based combat with enemy forces. The game features a deep character progression system, where characters level up, learn new skills, and equip various weapons and armor. The game's story is told through animated cutscenes and dialogue, featuring classic Gundam characters like Knight Gundam, Ryu Knight, and Zero Knight, as well as original characters created for the game.
The game's world is a vibrant fantasy setting, with castles, forests, mountains, and dungeons to explore. The game also features a "morale" system, where the party's morale affects their performance in battle, adding a strategic element to resource management. The game's visuals are colorful and detailed, with large, expressive sprites and detailed backgrounds. The soundtrack features orchestral and synth pieces that evoke the epic feel of a fantasy adventure.
SD Gundam Gaiden was a commercial success in Japan, capitalizing on the popularity of the Gundam franchise and the SD art style. It received positive reviews for its strategic depth and faithful adaptation of the source material. Angel and Bandai would continue to develop the SD Gundam Gaiden series, releasing several more games on the Super Famicom and other platforms. The game remains a classic among Gundam fans and RPG enthusiasts.
