Started reading Branden Sanderson's Mistborn, I only got a few chapters in and despite the writing being better than most LitRPG and the series being so litrpg adjacent (Low-power hero becomes the MC through getting some OP super rare skill) I found myself pretty quickly bored by it and am not sure why. I had trouble even bothering to listen to it this week and switched to listening to the Solo Leveling audiobook which, despite being not even a real book (but is instead a web novel / manga), has me locked in.
There's just something about this genre that is extremely engaging. I don't think it's the numbers, I think authors should move away from numbers and more toward S through E rank (or whatever) stats that are scaled with the character's tier or level. I think it's just that there is a system in place and a focus on progression and mechanics that grounds the entire plot. I also think the more I read the less I enjoy multiple POV stories, which LitRPG rarely has. I think it's also that totally broken mechanics, items, monsters, etc are simply expected and normal. Going back to even progression fantasy, everything just feels flat and one dimensional.
