Last Genesis is a classic turn-based RPG set on the continent of Atlia, a land shaped by centuries of war that has recently found stability under the cosmopolitan Atlian Union. Johann Kestler is a young man living quietly in the countryside whose stability ends when his father disappears. His search takes him across all of Atlia, where he eventually meets Jack Fleming — a student wrongly accused of murdering his headmaster — and Jean Versailles, a mysterious traveler who was arrested by the Union itself. Together, the three of them uncover a conspiracy that puts the entire world at risk. The game offers more than ten hours of content in a style that would be at home on the GBA, features many small player choices that alter both the story and the gameplay, and ends in one of six different ways depending on the path taken.
