Which was the first M-rated video game developed by Squaresoft/Square Enix?

Parasite Eve was the first M-rated video game developed by Squaresoft/Square Enix. This rating was justified due to its mature themes, intense violence, and explicit content. The game pushed boundaries in terms of horror and storytelling, creating a dark and gripping experience that resonated with mature gamers. Its success paved the way for subsequent M-rated titles from the company and solidified Squaresoft/Square Enix as a developer willing to explore more mature and provocative content in their games.
