I've read both ROTSSG and Rebirth of the thief who roamed the world and at first I thought the this novel is like your typical reincarnated person in the game story type but as I read further in the chapters I saw that the story became deeper, on all honesty there are grammar mistake here and there and sometimes it confuses me, but the author is compensating me with the good story arcs, as the other review said, the world building is a mess, at first but little by little it became clearer, I'm just looking at it in a new game perspective that the author don't want us to know the layout of the world because he himself is still exploring it. Final thoughts: At first you'll just see a generic type reincarnation game but as you go further down the novel you'll notice that the author is growing. Give it a try, if you love reincarnation games like the one that I mentioned then you will surely love this one too.
