I'm pretty picky myself when it comes to staying dedicated to them because I refuse to read something so poorly written that it doesn't make sense or is just really badly disguised fanfiction/plagiarism/AI generated. I will drop them really easily if they just start to lose the plot. Last Royal Road one I did like that was Moon Cultivation which was a cultivation story set on the moon, but the protagonist had absolutely no depth to them and the story itself was just "Jake is very special" - in retrospect the protagonist being named 'Jake Sullivan' should have tipped me off that it wasn't gonna be like, amazing, but hey - I'll read 160 chapters of mid sci-fi xiaxia before dropping it. But reading has always been my escape and I am the type of person who also reads actual books on my phone as well instead of scrolling social media when I'm waiting somewhere or on the train, so I just in general am willing to read some capital S slop for at least a couple chapters as long as the premise sounds entertaining.
I've actually been struggling to get back into The Wandering Inn, which is like over 12 million words at this point across 10 volumes (of which I've read up to like, the last dozen chapters of Vol 10 or so) because Pirateaba had to fucking reintroduce the stupid ass Christian [Prophet] character and ugh I don't really care to read several chapters from the perspective of some Christian freak and he's really boring and let me just be honest I don't think the way the plot has been developing since the beginning of Vol 10 has been great. Arguably the worst volume in the series and it is maddening to me because the 11 million words before that were some of my favorite fiction ever; especially considering it is a free web-serial I've read since 2016.
I think the way I read web serials (exclusively on my phone, exclusively in a browser tab-group meant for web-serials - no app, RoyalRoad ads blocked lol) helps a lot though in general. At the time of writing this I have 151 tabs in that group, 145 or so of them being a different RoyalRoad stories and the other 5 being other non-RoyalRoad web serials like TWI. I am only actively reading ~6 atm and the majority of the ones I'm not reading, I've either dropped/paused at some point due to getting bored/bad writing or otherwise have just clicked on from a shoutout in a different story & haven't actually checked out yet besides reading the blurb. So really easy for me to just scroll through them and go 'let's check out this story' if I'm not interested in catching up on whatever I'm currently reading or if I get sick of binging another.
I do the same with old fantasy series too; I've been working through Andre Norton's Witch World recently and the Guin Saga (via fan translation at least) but my phone has like at least 2-3gb of epubs of various sci-fi/fantasy series waiting to be read that I haven't even opened.
My slop cross to bear
