DanMachi fanfic

I want to say that I have seen similar works already written, this is just my version of the idea.

The idea is that you get a simulator either before or after the gods blessing. Whereafter you can simulate either the future of another world with talents, normally you can choose one or three out of three or ten random talents. Then when the main character starts the simulation, the main character gets a certain amount of information some person can use in the future(if you go with this idea remember to be careful about the information you gives in the text and what you don't and stick to it). After the simulation when the main character have fulfilled certain conditions, it could be live a certain amount of time or be so and so close to save the world, the main character can choose certain number of rewards. The rewards could be things like talents, experiences or abilities you get permanently. I'll Recommend making the simulated worlds nonpersonal and not permanent, to doffer the story to similar stories and to put more focus on the main world. It is also recommended to give the simulator restrictions such as the number of simulations every so often and how to get certain rewards such as having to get a certain score to get a certain level of talent.
