Honestly, lemmy and the fediverse as a whole will have natural growth and thats fine - mastodon has been around for like 8 years and is only recently getting a small amount of attention and mainstream usage. Like take the long view - like the really long view like 15 years from now. It’ll probably be huge, but until then we will just share memes and have a good time discussing stuff.
Something that I have ran into is the mono runtime for gaming, it has many complicated dependinces which can easily conflict with the main system. I just ended up making full containers for older mono versions to get old games to work anyways.
