There are several similar to this one, but if I'm honest, many of them are garbage.
For example, I remember reading one in which the protagonist had a system that forced him to simulate a life in another world and from that he would get rewards according to his progress. I'm talking about a complete simulation and not just a few words mentioning everything they did. So it looked interesting. However, I was disappointed to read that the said MC stopped using that system mechanic and instead assigned other people to use it, taking most of his earnings and giving them a measly reward.
In truth, that story made me empathize more with the secondary characters, who were actually making an effort to live their lives, instead of idle MCs.
