Steins;Gate
Steins;Gate is one of the best anime of the last decade, and almost instantly became a cult classic after its release. However, the anime is actually based on a fantastic visual novel developed by MAGES and Nitroplus.
Steins;Gate tells the story of Rintaro Okabe, a self-proclaimed mad scientist who accidentally discover the secret to time travel, and all of the baggage that comes with it. While the show starts off innocently enough, things quickly take a dark and psychological turn with some seriously weighty themes that only help to strengthen the characterization and storytelling.
A gripping story, stellar animation, tight pacing, and a memorable soundtrack are just a few of the reasons Steins;Gate is considered at the top of anime.
In a strange loop, the anime even inspired MAGES to go back and develop Steins;Gate Elite, adapting the original visual novel into a full-motion one that uses scenes from the anime.
