Hm. It really depends on what your goals are. A wizard in a robe & pointy hat and their plate armor knight companion walking past a row of vending machines will inevitably affect the tone of the story, but if you're aiming for that altered tone then it's not really too much is it?
Well, everything, but as I said it's a matter of personal taste. I'm not a fan of fucked up stuff. If that fits the tone of the story you're going for, however, then that's not something I can criticize.
Objectively, I do think there's more detail here than is practical for a story. The...
Eh...
Ehhhhhh.......
Sure, write it if you want, but as a matter of personal taste I am not likely to choose to continue reading a book that had all that in it.
Hm, I've seen some series that have combined litRPG & cultivation or have a character get a litRPG system that speeds up their cultivation. Having them as two completely separate systems isn't something I've seen before.

Hm, looks like the name Shub-Niggurath is certainly in the public domain. Aspects established for the character in stories published after 1930 might be up in the air, since there seems to be some confusion over whether Lovecraft's estate did the work to keep the copyright up to date. Still, if...

Hmmm.... Of course a world should be well designed, but as authors we should look for areas where the readers can do some of the work for us as well as consider what aspects are relevant enough to the plot to require filling out.
For example, if we have our protagonists meet a queen and her...
Hrrrm.... I half agree with this? I do agree that things in a character's life should have an effect on them, but how strongly that effect manifests is going to vary from character to character. From Karlin's description I also don't know if romance or attraction is relevant to the story to...
There's various sites where you can do so. The popular genres likely aren't something that will appeal to most people, but I've found a lot of enjoyable stories to read on Royal Road. Haven't gotten to the point of me publishing anything on there, but that's because I'm lazy.
Nope! You don't have to register anything for it to be under copyright. However, you're copyrighting a specific expression rather than an idea.
The wise cracking insect themed superhero isn't under copyright since it's an idea, but Spiderman is under copyright as a specific expression of that idea.
