LitRPG suck because those who write it usually don't even know how to properly RPG gameplay into a novel.
And don't get me started with "System".
It's pretty much the trope of immortal inside a ring all over again, but it's an AI waifu instead of a humble Old Man.
I still have to find LitRPG with pause button, graphics setting, water quality setting, difficulty setting, controller setting, volume option, brightness option, HUD, language setting, subtitles, and "EXIT" Button.
Not even savegame exist, despite the popular "Undertale" giving a good example of replayable Game RPG should look like.
It's pretty much just Overlord-but-worse all-over again. At least Tensei Slime had it's share of mini-politics as ruler with mini-Nation building.
