I found a big modded Minecraft server built around That Time I Got Reincarnated as a Slime. The goal is to recreate the Tensura world with a magitech vibe like Tempest. You start in the Capital City of Tempest and it was built by the community. There are Tensura characters walking around as NPCs and the screenshot shows stuff like Rimuru and Luminous and Testarossa and Ultima and Carrera as custom entities.
It runs on 1.19.2 and it is huge with 300 plus mods. There are over 2000 quests and a crazy amount of skills with their own quests to unlock them. You can pick from over 50 races and there are 500 plus evolutions plus custom dimensions. It also works like a standalone RPG even if you do not know the anime.
The main questlines are fully covered for Vanilla Minecraft and Minecolonies and Ice and Fire and Apotheosis and Create. The quests explain a lot so you do not have to alt tab all the time. There is a full economy system with shops and currency converting and skill mastering. There is also an Adventurers Guild where you start at F rank and work up to SS class by fighting monsters and stronger stuff.
