This is a very good and fair point. I did consider this and was beginning to actively investigate something like this already, specifically lemmy.zip. I have been pondering a move to something more appropriate for awhile now. Unfortunately the Mali situation is forcing my hand to act more quickly, and I wanted to pick an instance that has a known track record. The World admins have successfully run both lemmy.world as well as their mastodon instances. I do not know much about the gaming-centric instances and their admins enough to jump in blindly at this time. If I had more time to develop those connections with them, I would have done so (and was planning to do so).
I do think that something like a gaming-centric instance is the way forward long-term and supports the Fediverse’s values and it will be something I deeply consider when evaluating a potential future migration due to future circumstances or for something like a PS6 community establishment. If there were ever a way to more easily migrate communities, I will also consider this down the line.
