Full Bars In Another World!

Should I continue or restart?

(°'◇°')¡ hi again...
It's been a while, huh?
I haven't updated this story in about 3 years, and still get surprised when I see this getting votes and added to reading lists, and am thinking about continuing this story, but I don't like some of the things that I did in it, and want to rework it. I still enjoy the comedy, but reading back I'm not super happy with the mc and want to do some tweaking to the characters and story(even if it's only a couple of chapters) and I think I'd find it easier to restart from the beginning.

I want to try and get into writing again, because honestly when I've gone to my bookmarks of various websites, I've noticed I've read THOUSANDS of storys (O-O)
I always try to get into writing, but always get distracted by falling into old reading habits.

I have a few ideas for stories I want to tell, including:

This one, but with a more fleshed out... everything \(^-^)/

A traveller who goes across universes of many different genres, recording the different magicks he discovers and the people he meets.(fantasy adventure action romance)

And perhaps I'll try and to the story that I've always thought of, the isekai into the story of king Arthur's world, but after the legend became history, and things are... off.( dark fantasy action)

So I'd like to ask, if I truly start over this story, and the stories that I just mentioned, would you try reading any of them? (-_°)?
