Similarly to the post I made earlier on The Elder Scrolls, I may be missing a few communities that already exist due to lemm.ee being on a slightly behind server version - but on the chance that there isn’t already a Fire Emblem community here, I decided to fix that.
Lemmy.world is still running version 0.17.4, that might explain your issues.
In case you didn’t know, you can also browse communities from https://browse.feddit.de/
There is also lemmyverse.net/communities, and check my other comment. It is not due to the version difference.
