I considered this, but I do not have the resources to run my own instance. There are some gaming focused instances that are popping up, but for now the most established gaming communities are on lemmy.world. Plus, I dont know much about those instance admins to trust blindly diving in with them. I am very happy with the lemmy.world admins and think they are doing a great job. They also have a successful track record with their mastodon instance, sot I have confidence in them longer term.
I will keep this in mind for a future migration to something like PS6 (or if some other catastrophe comes along lol).
