I've never experienced either of those things but I guess the second one...? Anyways, Fantasy or Sci-Fi!
why not both? lol.. I'm currently writing one.. haha... fantasy with well explained logic... and that's where the sci-fi part comes in... non human or human protag?
To me, it all depends on the author skill, if the harem are well humanized and not carbon copy then left to the side then its acceptable, if not i'll just go with no romance at all... support fav creator financially or by help promoting if no money?
support fav creator financially...i'm not good with promoting 100+ chapters or 1000+ chapters?? (novels)
honestly depends on mood and genre or content of the novel... i don't remember last i started a new CN novel, and most long running ones that i read are either finished or dropped now... so i'll go with 100+ with a good closure or ending. worldbuilding heavy or character focus novel?
character focus, like their over the top reactions to things MC that hides their strength or flaunts it?
