Like the rest of the saga, it brings together on a single turn-based strategy board giant robots from very different series - from Mazinger to Gundam, by way of Getter Robo and Evangelion - with each franchise contributing its own cast, weapons, and transformations within a deep combat system highly respected in Japan. Like almost the entire main series, it remained exclusive to that market due to licensing issues.
For mecha anime fans it's one of the pinnacles of the turn-based strategy genre, though its heavy reliance on Japanese licenses kept it far from the West for years.
