Ok, I wanted to reply
@Mystic_Grasshopper first but since you called me out for some reason that I am unclear of, I want to ask what exactly am I getting called out for?
Is it the unnecessary part? If so, which part?
Rule of cool, if it sounds cool to someone then they do it.
The problem here is asking about if it is necessary immediately breaks the rule because the person asking didn't care enough to add it in from the start. But then it sounds too critical to say that to someone wanting to write into a new genre that has grown to a point to having conventions to it. I guess in essence one would more so ask if the story has a system which would want to reward or acknowledge its users in that way.
Yeah I somewhat get it after awhile.
I mean, it is his work, he can do whatever he want.
Which is why I feel that it is weird that he ask if he should put it in and not how to execute it.
@Alski and
@Tempokai already gave him some idea, so I should probably too.
Ps.
@Eldoria literally told the guy to just shove it in the glossary, which is my way of understanding that the titles aren't relavant to the plot of story and are just for fluff.
Assuming
@ThisAdamGuy isn't bothering to flip back to his completed chapters, Ctrl+h and insert, one viable option will be for "LitRPG System Update"
As in the inwork system literally update for now to include Titles and Achievements. And if the author wants, he can even have an epic moment where the system backlogs all the previous unrecorded completion and shove MC up the power level ladder.
