MMORPGs are kinda dead now compared to mid 2000s- early 2010s. Most of the good ones with a somewhat lively community are subscription based like FF14.
A modern and free MMO with a big community I'd recommend is Lost Ark. It's mechanics are also more welcoming to beginners.
I used to be addicted to FF14 cuz of its community. They had guilds like this manhwa, and I made online friends there that I still talk to today.
Lowkey able to find two such communities. You have to go to games or servers that seem dead but in actuality got a pretty dedicated fan base. One was on a small Minecraft server (forgot the name) and another was on a mobile game app called “a girl adrift” in the beginner channel. You’ll have to wait a bit until some people gather tho but sometimes a lot gather and it’s pretty active. Met a lot of cool and peculiar people there
Anime and mangas always display cool MMOs like this one, but the few I played were pretty cheap and scammy-like :/
Am I bad at finding them or do they just not exist? ┗( T﹏T )┛
