isekai_mokushiroku_mynoghra
Light novel and manga series set in a world that resembles a fantasy turn-based strategy (TBS) game. The protagonist reincarnated in an unknown world as the commander of the evil civilization Mynoghra, the weakest civilization from Eternal Nations, his favorite TBS game. With Mynoghra's hero unit Atou (isekai Mokushiroku Mynoghra) by his side, the two resolve to create a new nation in this world.
It's later revealed that Eternal Nation's rules aren't the only ones that apply to the world. Players and NPCs from many other different games have also been reincarnated and all of their systems work simultaneously, colliding with each other when they meet.
