This book borrows elements from various games and works, such as the Primordial World, various anime, and Stellaris. They're only used as inspiration for certain settings, though. The plot is completely original... probably, maybe, possibly. If anything seems familiar, it's purely a coincidence!
Brothers who like science fiction, like systems, and like to slowly upgrade and become stronger along the way, this book will not disappoint you.
