A 100+ mods list with minor configuration, a little element of horror sprinkled in, some magic, tech and a sprinkle of exploration.
Tested with 6 GB of ram allocated. Plays fine on singleplayer, but I'd recommend offloading some stuff to a server if possible.
There isn't much of a story to this modpack, but if I had to think of one it would probably be an isekai situation.
